Agur introduces himself as the son of Jakeh and addresses his oracle to Ithiel and Ucal (v. 1). He confesses with irony that he is more ignorant than any man, has no human understanding, has not learned wisdom and does not know the Holy One (vv. 2-3). He asks who has ascended to heaven and come down, who has gathered the wind in his fists, who has wrapped up the waters in a garment and who has established all the ends of the earth, and what his name and his son's name are (v. 4). Every word of God proves true, and he is a shield to those who take refuge in him; we are not to add to his words (vv. 5-6).
Then comes Agur's prayer: he asks for two things before he dies. Remove far from him falsehood and lying, and give him neither poverty nor riches but only the food he needs, lest he be full and deny the Lord or be poor and steal (vv. 7-9). Next he describes four kinds of people: those who curse their fathers, those who are pure in their own eyes yet unwashed of filth, those whose eyes are lofty and those who devour the poor (vv. 11-14). The leech has two daughters who cry, Give and Give (v. 15), and there are four things that never say, Enough: Sheol, the barren womb, the land never satisfied with water and fire (vv. 15-16).
Then come the things too wonderful: the way of an eagle in the sky, a serpent on a rock, a ship on the sea and a man with a young woman (vv. 18-19). Four things make the earth tremble: a servant who becomes king, a fool filled with food, an unloved woman who gets a husband and a maidservant who displaces her mistress (vv. 21-23). Four animals are small but exceedingly wise: ants, rock badgers, locusts and the lizard (vv. 24-28). The chapter ends with a warning to put your hand on your mouth if you have exalted yourself, for churning milk produces butter, pressing the nose produces blood and forcing anger produces strife (vv. 32-33).
