C. F. Keil and Franz Delitzsch on Proverbs 19:15

Pro 19:15 15 Slothfulness sinketh into deep sleep,      And an idle soul must hunger.

Regarding תּרדּמה and its root-word רדם, vid., at Pro 10:5. הפּיל, to befall, to make to get, is to be understood after Gen 3:21; the obj. על־האדם, viz., העצל, is naturally to be supplied. In 15b the fut. denotes that which will certainly happen, the inevitable. In both of its members the proverb is perfectly clear; Hitzig, however, corrects 15a, and brings out of it the meaning, “slothfulness gives tasteless herbs to eat.” The lxx has two translations of this proverb, here and at Pro 18:8. That it should translate רמיה by ἀνδρόγυνος was necessary, as Lagarde remarks, for the exposition of the “works of a Hebrew Sotades.” But the Hebrew literature never sunk to such works, wallowing in the mire of sensuality, and ἀνδρόγυνος is not at all thus enigmatical; the Greek word was also used of an effeminate man, a man devoid of manliness, a weakling, and was, as the lxx shows, more current in the Alexandrine Greek than elsewhere.
