Proverbs 15:15

Each of these verses turns on the heart, lêb (also written lêbâb). In Scripture the heart is the center of the whole person: the mind that understands, the feelings, the will that chooses, and the conscience. That is why the same word can hold joy in verse 13 and understanding in verse 14. Proverbs has already told us to guard it: “Keep thy heart with all diligence; for out of it are the issues of life” (Proverbs 4:23). It is also the heart with which God commands us to love him (Deuteronomy 6:5).

These verses belong to the collection of Solomon’s proverbs that begins in chapter 10, made up mostly of two-line sayings. In most of them the second line answers the first by contrast, joined by “but”, so that the wise and the foolish, the glad and the grieving, stand side by side and are easy to remember. Chapter 15 keeps returning to speech and to the inner life beneath it. It opens with “A soft answer turneth away wrath” (Proverbs 15:1), warns of the harm done by perverse speech (Proverbs 15:4), and praises the one who heeds instruction (Proverbs 15:5). Proverbs was given as practical teaching for living rightly among God’s people, handed on from elders to the young, and these three sayings carry that teaching into joy, grief and learning.

“A merry heart maketh a cheerful countenance.” The word for merry, sâmêach, means glad, blithe or joyful. The countenance, pânîym, is the face, the first place where the inner life shows. Gladness in the heart makes the face bright, pleasant and welcoming, and real joy within finds its way out.

The second line turns to sorrow. “Sorrow of the heart”, atstsebeth lêb, is grief, anguish or distress that comes from within. Its effect reaches the spirit, rûwach, a word for breath and life that here means a person’s inner vigor, courage and hope. The word for broken, nâkêʼ, comes from a root meaning smitten, and it describes something afflicted, crushed or wounded. A broken spirit, then, is a person whose strength and hope have been crushed, who is left dejected and listless. Joy shows on the face, and sorrow goes down to the spirit.

God made us so that the inner and outer life are bound together, and Proverbs says the same thing again with health in view: “A merry heart doeth good like a medicine: but a broken spirit drieth the bones” (Proverbs 17:22). Sorrow itself is a natural and often needed part of life in a fallen world. The warning of this proverb concerns sorrow that is allowed to consume a person until the spirit is crushed.

“The heart of him that hath understanding seeketh knowledge.” The person of understanding already has discernment and insight, and that very understanding makes them hungry for more. The verb bâqash means to search out, seek or require, and it describes a deliberate, earnest pursuit. Wisdom is found by those who go looking for it. Proverbs 2 describes the search in the same spirit: “If thou seekest her as silver, and searchest for her as for hid treasures”, and it names where the search ends, “For the LORD giveth wisdom: out of his mouth cometh knowledge and understanding” (Proverbs 2:1–6).

The knowledge sought, daʻath, is knowing truth by experience and moral acquaintance, the kind of understanding that leads to right living. It begins with God: “The fear of the LORD is the beginning of knowledge” (Proverbs 1:7). The blessed man of Psalm 1 shows what this seeking looks like day by day: “his delight is in the law of the LORD; and in his law doth he meditate day and night” (Psalm 1:1–2).

“But the mouth of fools feedeth on foolishness.” The word ʼivveleth comes from the word for a fool, ʼĕvîl, and means silliness or folly, carrying a moral and mental failing that leads to senseless and even destructive conduct. The fools of Proverbs are dull of mind, resistant to wisdom and confident in their ignorance. The picture is of eating. The fool takes folly in without discernment, lives on it, and gives it back out in what he says, content with what is empty. The heart seeking and the mouth feeding each stand for the whole person, and the two lines show two people heading in opposite directions.

Jesus teaches the same link between the inner life and speech: “those things which proceed out of the mouth come forth from the heart; and they defile the man” (Matthew 15:18–19). What we feed on shapes who we become, and in time it is heard in our words.

“All the days of the afflicted are evil.” The afflicted person, ʻânîy, is one pressed down, a word that comes from ʻânâh, to depress or afflict. Strong’s gives its sense as “depressed, in mind or circumstances”, and it covers the humble, the lowly, the needy and the poor. For such a person every day is raʻ, a word for what is bad or evil, in the natural sense as well as the moral one. It is used of adversity, calamity and what is troublesome, grievous or unpleasant, and here it describes days that are hard and burdensome. Weighed down within, the afflicted find that the heaviness colors every day.

“But he that is of a merry heart hath a continual feast.” Here merry translates ṭôwb, the ordinary word for good in its widest sense, which can mean beautiful, cheerful, glad, at ease or pleasant. The phrase is literally “good of heart”. Verse 13 uses a different Hebrew word for merry, sâmêach, so the two verses share the English word while both speak of a glad heart. The feast, mishteh, was in Israel a time of celebration, plenty and fellowship. The word continual, tâmîyd, means constant or perpetual. The glad heart lives as though the feast never ends.

Both lines speak broadly on purpose. “All the days” and “continual” sweep wide to make the contrast plain, and the proverb is describing the whole tone of a life, which does not mean misery or celebration in every single moment. A heart weighed down finds every day heavy, and a glad heart finds a feast even in plain days and hard ones.

These verses give us an honest picture of ourselves. Joy and sorrow both reach deep, and what we take into our hearts comes back out in our faces, our words and our days. They show who God is as well. He is the Creator who made us whole, with the inner and outer life bound together, and he cares about the state of the heart as well as the deeds that flow from it. He draws near to the broken in spirit and gives a new heart and a new spirit. He gives wisdom out of his own mouth to those who seek it, and he fills his people with joy by his Spirit. The continual feast of verse 15 is a table he spreads, and in Christ it lasts for ever.
