Let them be yours alone, never to be shared with strangers.
BSB
ASV

KJV
Let them be only thine own, and not strangers’ with thee.
Let them be only thine own - The off-spring of a legitimate connection; a bastard brood, however numerous, is no credit to any man.
By figures, in which well, cistern, and fountain [Pr 5:15, 18] represent the wife, and rivers of waters [Pr 5:16] the children, men are exhorted to constancy and satisfaction in lawful conjugal enjoyments. In Pr 5:16, fountains (in the plural) rather denote the produce or waters of a spring, literally, "what is from a spring," and corresponds with "rivers of waters."
Rare words are the text's own signal of a deliberate thread: the fewer the occurrences, the more the places it appears belong together.
