21 To have a fool for a child brings grief; there is no joy for the parent of a godless fool.
21 He that begetteth a fool doeth it to his sorrow: and the father of a fool hath no joy.
21 He who sires a fool gets himself sorrow, and the father of a fool has no joy.
21 Having a fool for a child is misery; it's no fun being the parent of a dolt.
21 He who begets a scoffer does so to his sorrow, And the father of a fool has no joy.
21 It is painful to be the parent of a fool; there is no joy for the father of a rebel.

(Read Proverbs 17:21)
This speaks very plainly what many wise and good men feel very strongly, how grievous it is to have a foolish, wicked child.
