The first hemistich is a variation of Proverbs 10:1-32. I (where see note). Keepeth company with; literally, feedeth, as Proverbs 28:7. Harlots (see on Proverbs 6:26). Such vice leads to the wasting of substance (Luke 15:13), and the great sorrow of the parent.
Septuagint, "But he that pastureth ( ποιμαίνει) harlots shall waste wealth."
