C. F. Keil and Franz Delitzsch on Proverbs 21:17

Pro 21:17 17 He who loveth pleasure becometh a man of want;      He who loveth wine and oil doth not become rich.

In Arab. samh denotes the joyful action of the “cheerful giver,” 2Co 9:7; in Heb. the joyful affection; here, like farah, pleasure, delight, festival of joy. Jerome: qui diligit epulas. For feasting is specially thought of, where wine was drunk, and oil and other fragrant essences were poured (cf. Pro 27:9; Amo 6:6) on the head and the clothes. He who loves such festivals, and is commonly found there, becomes a man of want, or suffers want (cf. Jdg 12:2, אישׁ ריב, a man of strife); such an one does not become rich (העשׁיר, like Pro 10:4, = עשׂה עשׁר, Jer 17:11); he does not advance, and thus goes backwards.
