A fool's lips enter into contention,.... That is, between others, when he has nothing to do with it; but he must be meddling, and make himself a party in the contention, which is an argument of his folly; he says things which occasion disputes, raise contentions among men, and provoke to wrath and anger. The Septuagint version is, "the lips of a fool lead him to evils": for, as they lead him to contention and strife, the issue of that is confusion and every evil work; and his mouth calleth for strokes: as he stirs up and encourages contention, so he proceeds to blows, and excites others to them; from words he goes to blows, and, by the ill and provoking language of his mouth, gets many a blow to himself. Jarchi seems to understand it of chastisement, from the hand of God; see Pro 26:3.
