Proverbs 27:1-3

Expanded Bible

27 Don’t brag about tomorrow;
you don’t know what ·may happen then [^Lthe day may bear/ bring forth].

² Don’t praise yourself. Let ·someone else [another; a stranger] do it.
Let the praise come from a ·stranger [outsider] and not from your own mouth [Jer. 9:23–24; 1 Cor. 1:31; 2 Cor. 10:17].

³ Stone is heavy, and sand is weighty,
but ·a complaining fool [or the irritation/frustration caused by a fool] is ·heavier [worse] than either.
