Proverbs 18:6

6 The lips of a fool meddle themselves with chidings; and his mouth stirreth strives. (A fool's lips mix, or mingle, themselves in with arguments; and his mouth stirreth up strife.)

Proverbs 18:6 Meaning and Commentary

Proverbs 18:6

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 ( Proverbs 26:3 ) .

Proverbs 18:6 In-Context

4 Deep water is the words of the mouth of a man; and a strand floating over is the well of wisdom. (Words from a person's mouth can be like deep water/can be as deep as the water; and the well of wisdom is like a stream flowing over.)

5 It is not good to take the person of a wicked man in doom, that thou bow away from the truth of doom. (It is not good to favour a wicked person, so that thou turn away from the truth in judgement.)

6 The lips of a fool meddle themselves with chidings; and his mouth stirreth strives. (A fool's lips mix, or mingle, themselves in with arguments; and his mouth stirreth up strife.)

7 The mouth of a fool is [the] defouling of him; and his lips be the falling of his soul.

8 The words of a double-tongued man be as simple; and they come unto the inner things of the womb. Dread casteth down a slow man; forsooth the souls of men turned into women's condition shall have hunger. (A gossip's words be tasty; and they go down into the innermost parts. Fear casteth down the lazy; and those who be timid shall have hunger.)
