The Pulpit Commentary on Proverbs 29:22

An angry man stirreth up strife. This is a variation of Proverbs 15:18 and Proverbs 28:25 (which see). A furious man aboundeth in transgression. "A furious man" is a passionate person, who gives way to violent fits of anger (Proverbs 22:24). Such a man both makes enemies by his conduct and falls into manifold excesses of word and action while under the influence of his wrath. "The wrath of man worketh not the righteousness of God" (James 1:20). The Greek gnome says—

ὀργὴ δὲ πολλὰ δρᾷν ἀναγκάζει κακά

And again—

πόλλ ἔστιν ὀργῆς ἐξ ἀπαιδεύτου κακά

"Unchastened anger leads to many ills."

Septuagint, "A passionate man diggeth up sin"—a forcible expression, which is not unusual in reference to quarrels.
