Compare Proverbs 17:21. Here is added a reference to the sorrow which the folly of a child brings especially to the mother.

A foolish son is a grief to his father,.... Because of his folly and wickedness, and the ruin he is bringing himself to;

and bitterness to her that bare him; a cause of bitterness of soul to his mother, more distressing than the bitter pains with which she brought him forth into the world. Jarchi, by the father, understands the blessed God; and by her that bare him, the congregation of Israel; to whom Jeroboam, the son of Nebat, was bitterness, who caused Israel to sin; see Proverbs 10:1.

The series of proverbs, v. 25-18:2, begins and closes in the same way as the preceding, and only Proverbs 17:26 stands by itself without apparent connection.

This verse begins connecting itself with Proverbs 17:21 :

A grief to his father is a foolish son,

And a bitter woe for her that bare him.

The ἅπ. λεγ. ממר is formed from מרר (to be bitter, properly harsh), as מכס from כּסס. The Syr. and Targ. change the subst. into participles; some codd. also have ממר (after the forms מחל, מסב, מפר, מרע), but as may be expected in 25a, מבעיס. The dat. obj. instead of the accus. may be possible; the verse immediately following furnishes a sufficient example of this.

A foolish son is a grief to his father, and bitterness to her that bare him.

25. a grief-or cross, vexation (compare Pr 17:21; 10:1).

17:19. If we would keep a clear conscience and a quiet mind, we must shun all excitements to anger. And a man who affects a style of living above his means, goes the way to ruin. 20. There is nothing got by ill designs. And many have paid dear for an unbridled tongue. 21. This speaks very plainly what many wise and good men feel very strongly, how grievous it is to have a foolish, wicked child. 22. It is great mercy that God gives us leave to be cheerful, and cause to be cheerful, if by his grace he gives us hearts to be cheerful. 23. The wicked are ready to part with their money, though loved, that they may not suffer for their crimes. 24. The prudent man keeps the word of God continually in view. But the foolish man cannot fix his thoughts, nor pursue any purpose with steadiness. 25. Wicked children despise the authority of their father, and the tenderness of their mother. 26. It is very wrong to find fault for doing what is duty. 27,28. A man may show himself to be a wise man, by the good temper of his mind, and by the good government of his tongue. He is careful when he does speak, to speak to the purpose. God knows his heart, and the folly that is bound there; therefore he cannot be deceived in his judgment as men may be.
