Proverbs 3:4

“My son” is how the father addresses his child again and again in the opening chapters of Proverbs (Proverbs 1:8, Proverbs 2:1). The word bên is the ordinary Hebrew word for a son, and here it carries both a father’s love and a father’s authority. In Israel the family, and the father above all, was where a child learned to live rightly before God, and Proverbs hands on its wisdom in that setting, as a treasured legacy from one generation to the next. Behind the father’s voice stands the LORD, since the whole book rests on the truth that “The fear of the LORD is the beginning of knowledge” (Proverbs 1:7). The father’s teaching is God’s wisdom, given with a parent’s care for the child’s good.

These verses open a run of teaching that goes on through Proverbs 3:1–12. Proverbs 1 and Proverbs 2 call the son to wisdom in broad terms. Here the father moves on to particular commands, and each one comes with a promise. Across Proverbs 3 those promises include long life, peace, favour and plenty.

Verse 2 begins with “For”, which ties the promise to the command. The “they” who “add” are the law and the commandments of verse 1, so the father pictures his teaching itself as giving good things to the one who keeps it. The verb yâçaph means to add or increase.

The first two gifts say the same thing twice for weight. “Length of days” joins ʼôrek, length, to yôwm, day, and together they mean long life. “Long life” is literally “years of life” in Hebrew, with shâneh for years and chay for life, so days and years stand side by side. Israel prized a full lifespan, brought to its natural end, as one of the great blessings of God.

The third gift is peace, shâlôwm. It names a state of completeness, soundness, welfare, peace and safety, and it covers the whole of life: a person sound in body, secure in his home, at one with his neighbours and right with God.

These promises echo the covenant God made with Israel. The fifth commandment, “Honour thy father and thy mother”, carries the promise “that thy days may be prolonged” (Deuteronomy 5:16), which fits a passage where a son is listening to his father. Moses set life and death before Israel and urged them to choose life by loving and obeying the LORD (Deuteronomy 30:19–20), and Deuteronomy 28 sets out the blessings of obedience beside the curses of disobedience. A psalm asks who desires life and many days, and answers with a life that departs from evil and seeks peace (Psalm 34:12–14). Later in Proverbs, Wisdom herself says that by her the days are multiplied (Proverbs 9:11).

Verse 3 names two qualities the son must hold on to. Mercy is cheçed, often rendered “steadfast love”, “lovingkindness” or “loyal love”. It is faithful kindness, the goodness of someone who keeps faith within a relationship, and it shows itself in compassion and practical help. Truth is ʼemeth, from a root meaning to be firm, and it means stability, certainty and truth. A person of ʼemeth is reliable, and his words and deeds hold together.

“Let not mercy and truth forsake thee” speaks of them as companions who could slip away. They stay by care and practice, and the father asks his son to keep them close just as he asked him to keep his law in verse 1.

He gives two pictures of how close. “Bind them about thy neck” calls up an ornament worn at the throat, always on the body, prized, and seen by everyone. Mercy and truth are to be the son’s adornment, visible in how he deals with others. “Write them upon the table of thine heart” goes inward. The word for table is lûwach, a tablet for writing, the word used for the “tables of stone” on which God wrote his law and commandments (Exodus 24:12). Jeremiah uses the same picture for sin, which is “graven upon the table of their heart” (Jeremiah 17:1). Whatever is written on the heart becomes part of a person, and the father wants mercy and truth inscribed there for good. The neck and the heart together mean the whole person, outward conduct and inner character alike.

Verse 4 gives the result: “So shalt thou find”. The verb mâtsâʼ means to find or attain. The one who keeps the father’s teaching and holds mercy and truth close comes to find two things.

The first is favour, chên, which means graciousness, favour or charm. It is goodwill and acceptance, being regarded with kindness. Before God it is his gracious approval, and among people it is their trust and respect. Scripture says that “Noah found grace in the eyes of the LORD” (Genesis 6:8), and it tells of Joseph, who found grace in Potiphar’s sight and was made overseer of his house (Genesis 39:4). In Israel’s communities a good name mattered greatly, and favour with others could bring protection, promotion and standing.

The second is “good understanding”. The noun is sekel, from a verb meaning to be prudent or to act wisely, and it means intelligence, discretion and prudence. Joined with ṭôwb, good, it describes sound judgment that leads to right action. Knowledge (da’at) is truth known, and understanding is the skill of applying it wisely to real decisions and relationships. God gave Daniel and his friends “knowledge and skill in all learning and wisdom” (Daniel 1:17).

“In the sight of God and man” puts God first. Right standing with him comes before the respect of people, and it often brings that respect with it, for God’s covenant blessings on obedience reached into every part of life (Leviticus 26, Deuteronomy 28). Scripture says the boy Samuel “was in favour both with the LORD, and also with men” (1 Samuel 2:26), and it uses nearly the same words of the boy Jesus: “And Jesus increased in wisdom and stature, and in favour with God and man” (Luke 2:52).

Like the promise of verse 2, this describes the path wisdom ordinarily takes. The actions of others and God’s own purposes shape how it works out in a given life, and the character that wisdom forms remains the surest way to be well regarded.

The call to keep the commandments with the heart and to write mercy and truth upon it looks forward to God’s promise through Jeremiah: “I will put my law in their inward parts, and write it in their hearts” (Jeremiah 31:33). The letter to the Hebrews applies that promise to the new covenant in Christ (Hebrews 8:10), and Paul says that believers are a letter “written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart” (2 Corinthians 3:3). What the father asks of his son, God brings about by his Spirit, who works in us “both to will and to do of his good pleasure” (Philippians 2:13).

Jesus is the Son who kept his Father’s law perfectly. He came to fulfil the law (Matthew 5:17–18), and he said that his food was to do the will of the one who sent him (John 4:34). In him mercy and truth meet in one person: the Word was made flesh, “full of grace and truth” (John 1:14). God showed his love in that Christ died for us while we were yet sinners (Romans 5:8), and Jesus called himself the truth (John 14:6).

Christ is “the power of God, and the wisdom of God” (1 Corinthians 1:24), the one “in whom are hid all the treasures of wisdom and knowledge” (Colossians 2:3). He grew in favour with God and man, and through his death (John 19:30) and his resurrection (Romans 4:25) he brings us into his own standing with the Father. God made him to be sin for us, “that we might be made the righteousness of God in him” (2 Corinthians 5:21). So the favour with God that verse 4 promises comes to us as a gift in Christ, and the Spirit gives us wisdom to live so that others see our good works and glorify our Father in heaven (Matthew 5:16).

These four verses show us God as a Father who teaches his children, speaking with love and with authority at once. His law is a gift handed down for our good, and he wants it held in the heart, where thoughts, desires and choices begin. He adds long life and peace to those who keep it, and his own character, abundant in mercy and truth, is the pattern he writes on his people. The favour he promises, first with himself and then with others, has come to us fully in his Son, who kept the law, embodied mercy and truth, and grew in favour with God and man. What the father asks in these verses, God by his Spirit writes on the hearts of those who belong to Christ, and a life of remembering his word and holding fast to mercy and truth rests on that gift.
