John Gill Commentary Proverbs 23:6

"Eat thou not the bread of him that hath an evil eye, Neither desire thou his dainties:" — Proverbs 23:6 (ASV)

Eat you not the bread of [him that has] an evil eye A sordid covetous man, that grudges every bit that is eaten, in opposition to a man of a good eye, or a bountiful one, that is liberal and generous, (Proverbs 22:9); if he invites to a meal, do not accept of it, sit not down at his table to eat with him: neither desire you his dainty meats or savoury food, so as to lust after it; (See Gill on Proverbs 23:3).
