שִׂפְתֵ֣י כְ֭סִיל יָבֹ֣אֽוּ בְרִ֑יב וּ֝פִ֗יו לְֽמַהֲלֻמ֥וֹת יִקְרָֽא׃
A fool’s lips enter into contention, And his mouth calleth for strokes.
Rashi on Proverbs
The lips of a fool will enter a quarrel All his matters come about with an expression of quarreling.
Rashi on Proverbs
and his mouth calls out for blows He calls pains to come upon himself.
