John Gill Commentary Proverbs 30:11

"There is a generation that curse their father, And bless not their mother." — Proverbs 30:11 (ASV)

[There is] a generation [that] curses their father A sort of men that neither fear God nor regard men; and are so inhuman as to be without natural affections to their parents; have no reverence of them, love to them, nor give them any honour or obedience; so far from it, that they curse their father that begot them; imprecate on him all the evils in life they can think of, and wish him out of the world;

and does not bless their mother ; cannot give her a good word, who bore them, and brought them up in the most tender and indulgent manner; yea, so unnatural as to curse her also, for that is intended by this way of speaking; see (Proverbs 30:17) .
