Augustine of Hippo — Commentary on Scripture

And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.

For while there remains any remnant of the lust of the flesh, to be kept in check by the rein of continence, God is by no means loved with all one’s soul. For the flesh does not lust without the soul, although it is the flesh which is said to lust, because the soul lusts carnally. In that perfect state the just man shall live absolutely without any sin, since there will be in his members no law warring against the law of his mind. But wholly will he love God, with all his heart, with all his soul and with all his mind, which is the first and chief commandment.

The number three has an intrinsic relation to the mind. This may be understood from the text in which we are commanded to love God in a threefold manner, with the whole heart, with the whole soul, with the whole mind.

Therefore the supreme and true wisdom is in that first commandment: “You shall love the Lord your God with your whole heart and with your whole soul.” From this it follows that wisdom is love of God, which is “poured forth in our hearts,” not otherwise than “by the Holy Spirit who is given to us.” But “the fear of the Lord is the beginning of wisdom,” and “there is no fear in love, but perfect love casts out fear.”

Deuteronomy 6:13 · 2 passages

Thou shalt fear the LORD thy God, and serve him, and shalt swear by his name.

What is to be said of justice in its relation to God? As the Lord says, “No man can serve two masters,” and the apostle rebukes those who serve the creature rather than the Creator, so had it not been said before in the Old Testament: “You shall adore the Lord your God and him only shall you serve”? But what need is there to say more about this here since the Scriptures are full of such texts? Justice then offers this rule of life to the lover we are describing: that he serve with gladness the Lord whom he loves, that is to say, the supreme good, the supreme wisdom, the supreme peace; and with respect to all other things, that he govern those which are subject to him and endeavor to subject all else to the same rule. This rule of life is confirmed, as we have shown, by the authority of both Testaments.

Whoever yields assent to the supreme authority of divine Scripture should first examine these words: “The Lord your God shall you adore, and him only shall you serve.” In Greek the expression used does not signify the service owed to human masters but that which is offered to God, called latreia. Thus idolatry is rightly condemned because the latreia which is due to the true God alone is offered to idols. It does not say, “You shall adore only the Lord your God,” but it says, “And him only shall you serve.” It used the word only with “you shall serve,” meaning, no doubt, that service which is called latreia. To this service belong temple, sacrifice, priest, and other like attributes.

Deuteronomy 7:5

But thus shall ye deal with them; ye shall destroy their altars, and break down their images, and cut down their groves, and burn their graven images with fire.

When you have received lawful authority, do all this. Where authority has not been given to us, we don’t do it; where it has been given, we don’t fail to do it. Many pagans have these abominations on their estates. Do we march in and smash them? The first thing we try to do is to break the idols in their hearts. When they too become Christians, they either invite us in to perform this good work or else they get in first with it before us. The thing we have to do now is pray for them, not get angry with them.

Deuteronomy 8:4 · 2 passages

Thy raiment waxed not old upon thee, neither did thy foot swell, these forty years.

If the garments of the Israelites could last without wearing out for so many years in the desert and the hides of dead animals could continue undestroyed for so long a time in their shoes, surely God can extend the quality of incorruption in certain bodies for as long as he wills. I think therefore that the body of the Lord is the same now in heaven as it was when he ascended into heaven.

God granted to the garments of the Israelites their proper state without any damage for forty years. If so, how much more does he grant a very happy temperament of certain state to the bodies of those who obey his command until they may be turned into something better? This embetterment occurs not by the death of man, by which the body is deserted by the soul, but by a blessed change from mortality to immortality, from an animal to a spiritual quality.

Deuteronomy 9:9

When I was gone up into the mount to receive the tables of stone, even the tables of the covenant which the LORD made with you, then I abode in the mount forty days and forty nights, I neither did eat bread nor drink water:

This is why Moses fasted for forty days, and Elijah, and the Mediator himself, our Lord Jesus Christ: because in this time-bound state of ours restraint from bodily attractions and allurements is very necessary. The people also spent forty years wandering in the desert, and forty days of rain produced the flood. The Lord spent forty days after his resurrection with his disciples, to convince them of the reality of his risen body. This suggests that in this life, in which we are in exile away from the Lord, the number forty stands, as I have just said, for our need to celebrate the memorial of the Lord’s body, which we do in the church until he comes.

Deuteronomy 12:3

And ye shall overthrow their altars, and break their pillars, and burn their groves with fire; and ye shall hew down the graven images of their gods, and destroy the names of them out of that place.

Give no credit to their words, neither be afraid of them. They say that we are enemies of their idols. So be it; may God give them all into our power, as he has already given us what we have broken down. For I say this, beloved, that you may not attempt to overcome those which it is not lawfully in your power to overcome. It is the way of ill-regulated men and the mad Circumcelliones to be violent when they have no power and to be ever eager to die without cause. You heard what we read to you, all of you who were present in the Mappalia: 2 “When the land shall have been given into your power”—he says first “into your power” and so enjoins what is to be done—“then you shall destroy their altars and break in pieces their groves, and hew down all their images.” When the power has not been given us, do not do it; when it is given, do not neglect it.

Deuteronomy 13:3 · 3 passages

Thou shalt not hearken unto the words of that prophet, or that dreamer of dreams: for the LORD your God proveth you, to know whether ye love the LORD your God with all your heart and with all your soul.

Take, for instance, the text “God tempts no one”: it cannot be understood as meaning every kind of temptation but only of a particular kind which God doesn’t tempt anyone with. Otherwise that other text, “the Lord your God is tempting you,” would be false. Otherwise too we might be denying that Christ is God or that the gospel is not telling the truth when we read that he questioned one of the disciples, “tempting him, but he himself knew what he was going to do.” You see, there is a temptation that leads to sin, and in that way God tempts no one. Then there is a temptation or testing that proves the quality of faith, and that way even God is prepared to tempt people. In the same sort of way, when we hear “whoever blasphemes against the Holy Spirit,” we shouldn’t take it as meaning every kind of blaspheming, just as in the other case we don’t understand every kind of tempting.

He permits us to be tested not in order that he, for whom nothing lies hidden, might know but in order that he might make us know the extent of our progress in love for him. According to this same mode of speech our Lord also says that he does not know the day or the hour of the end of the world. What can there be that he does not know? He was concealing it from the disciples for their benefit, and he said that he did not know it because he was causing them not to know by concealing it.

God is said to know even when he causes someone to know, as it has been written: “The Lord your God puts you to the test that he might know if you love him.” Now this manner of speaking does not mean that God does not know; rather, [it was said] in order that people might know how far they have progressed in the love of God—a thing which is not fully recognized by them except by way of the testings which come about. As for the expression “he puts to the test,” it means that God permits testing. Therefore when it is also said that God does not know, this means either that he does not approve (i.e., does not recognize [as conformable to] his discipline and teaching), as it has been said: “I do not know you.” Or [it means] that he causes people not to know for their own good, because it serves no useful purpose for them to know. Accordingly the text “the Father alone knows” is correctly grasped if understood to say that he causes the Son to know, and the text “the Son does not know,” if understood to say that the Son causes men not to know (i.e., does not disclose to them what would ser…

Deuteronomy 17:11

According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall shew thee, to the right hand, nor to the left.

Just as a person has to pick his way between fire and water so as to be neither burned nor drowned, so we should steer our way between the pinnacle of pride and the whirlpool of sloth, as it is written, “turning neither to the right nor to the left.” For there are some who, through fear of being carried up to the heights on the right, slip and are drowned on the left. Others … fear to be sucked in by the soft ease of sloth on the left and are ruined and destroyed by the ostentation of boasting on the other side, and [they] vanish into smoke and ashes.

Deuteronomy 18:15

The LORD thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;

“Like me,” says Moses. This means according to the form of the flesh, not to the eminence of majesty. Therefore we find the Lord Jesus called a prophet. Accordingly that woman is no longer greatly in error when she says, “I see that you are a prophet.” She begins to call her husband, to exclude the adulterer. “I see that you are a prophet.” And she begins to ask about a thing that constantly disturbs her.

Deuteronomy 19:15 · 2 passages

One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.

Therefore if a people composed of a great multitude was found a false witness, how must it be understood, “In the mouth of two or three witnesses every word shall stand,” except that in this way. The Trinity, in which is unending stability of truth, was revealed through a mystery. Do you want to have a good case? Have two or three witnesses, the Father and the Son and the Holy Spirit.

As a matter of fact, a single witness generally speaks the truth, while a mob may tell lies. And the world, in its conversion to Christianity, believed one apostle preaching the gospel rather than the mistaken multitude who persecuted him.

Deuteronomy 23:24

When thou comest into thy neighbour's vineyard, then thou mayest eat grapes thy fill at thine own pleasure; but thou shalt not put any in thy vessel.

Let all the servants of God grant [the monks] permission to enter their fields whenever they wish and to depart when well fed and satisfied. This is according to the law given to the people of Israel that no one should arrest a thief in his fields unless he wished to take something away with him. Rather, the owner of the field should permit him who had touched nothing but what he had eaten to depart free and unpunished.

Deuteronomy 24:1

When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.

The Lord explains the intention of the law, which required a bill of divorce in every case where a wife was put away. The precept not to put away a wife is the opposite of saying that a man may put away his wife if he pleases, which is not what the law says. On the contrary, to prevent the wife from being put away, the law required this intermediate step, that the eagerness for separation might be checked by the writing of this bill and the man might have time to think of the evil of putting away his wife.

Deuteronomy 25:5

If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her.

In the third book, then, when I was solving the question of how it was possible for Joseph to have two fathers, I indeed said that “he was begotten by one and adopted by the other.” But I should have mentioned too the kind of adoption, for what I said sounds as if another living father had adopted him. The law, however, also adopted the children of the deceased by ordering that “a brother marry the wife” of his childless, deceased brother and “raise up seed” by the same woman “for his deceased brother.” In this way the explanation of this matter of the two fathers of one man is indeed made clearer.
