Proverbs 13:2

“A man shall eat good by the fruit of [his] mouth, etc.] Or, “of the mouth”; either another’s or his own, since the word his is not in the text; though it is supplied by the Targum, Aben Ezra, the Vulgate Latin, and Syriac versions, as by us. The Septuagint and Arabic versions render it, “shall eat of the fruits of righteousness”. I should choose to translate the whole thus: “a good man shall eat of the fruit of his mouth”: so Aben Ezra interprets it, “a good man shall eat”; and so the Septuagint, Syriac, and Arabic versions render it. The sense is, that a good man brings forth good things out of the good treasure of his heart by his mouth; which not only minister grace to the hearers, and…”

“shall eat--that is, obtain (Pro 12:14). transgressors--as in Pro 2:22. violence--or, "mischief" to themselves.”

“Shall eat - Shall receive comfort, and benefit by his wise and profitable discourses. Proverbs 13:6”

“eat: Pro 12:14, Pro 18:20 the soul: Pro 1:11-13, Pro 1:18, Pro 1:31, Pro 4:17, Pro 10:11; Psa 75:8, Psa 140:11; Jer 25:27-31; Hab 2:8, Hab 2:17; Rev 16:6 Proverbs 13:3”

“2 From the fruit of the mouth of a man he himself enjoys good; But the delight of the godless is violence. 2a = Pro 12:14, where ישׂבּע for יאכל. A man with a fruit-bringing mouth, himself enjoys also the blessing of his fruit-producing speech; his food (cf. βρῶμα, Joh 4:34) is the good action in words, which in themselves are deeds, and are followed by deeds; this good action affords enjoyment not merely to others, but also to himself. Ewald and Bertheau attract יאכל to 2b; so also does Fleischer: "the violence which the בּגדים wish to do to others turns back upon themselves; they must eat it also, i.e., bear its evil consequences." The thought would then be like Pro 10:6 : os improborum…”
