Proverbs 30:5-6
God's word is perfectly reliable and must not be altered.
5 “Every word of God is flawless. He is a shield to those who take refuge in him.
6 Don’t you add to his words, lest he reprove you, and you be found a liar.
God's word is perfectly reliable and must not be altered.
To affirm the complete reliability of God's revealed word and warn against altering divine revelation.
Proverbs 30:5-6 follows Proverbs 30:2-4, where Agur confesses his lack of wisdom and asks a series of questions exposing human inability to master heavenly knowledge, wind, waters, earth, divine name, and the Son. Verses 5-6 provide the necessary theological answer: God’s word is flawless, and human beings must not add to it. This creates a decisive movement in Proverbs 30 from human limitation to divine revelation. The passage also prepares for Agur’s prayer in Proverbs 30:7-9, where dependence on God’s word becomes dependence on God’s provision and preservation from falsehood. The sequence is tight: human wisdom is limited, God’s word is pure, added words are dangerous, and the wise respond with prayer.
In Israel’s wisdom tradition, divine speech was the boundary and source of true wisdom. Agur’s confession of limitation leads naturally to trust in the purity of God’s word. The warning not to add to God’s words reflects a broader covenant concern: Israel must not alter the LORD’s commands, follow false prophets, invent unauthorized worship, or speak as though human words carry divine authority when God has not spoken.
The Sayings of Agur: Humility, the Word of God, Contentment, Wonder, and the Limits of Human Wisdom
Wisdom begins with humble confession before the Holy One, trusts the flawless word of God, prays for truthful contentment, learns from creation, rejects arrogance and greed, and restrains self-exalting speech before it produces strife.
