18:20 From the fruit of a person’s mouth 1 his stomach is satisfied, 2
with the product of his lips is he satisfied.
1 sn Two images are used in this proverb: the fruit of the mouth and the harvest of the lips. They are synonymous; the first is applied to the orchard and the second to the field. The “mouth” and the “lips” are metonymies of cause, and so both lines are speaking about speech that is productive.
2 tn Heb “his midst.” This is rendered “his stomach” because of the use of שָׂבַע (sava’, “to be satisfied; to be sated; to be filled”), which is usually used with food (cf. KJV, ASV “belly”).
sn Productive speech is not just satisfying – it meets the basic needs of life. There is a practical return for beneficial words.
