For they shall eat, and not have enough
Namely, the priests; for of them the words are continued, who ate of the sacrifices of the people, and of feasts made in honour of idols; and yet, either what they ate did not satisfy or nourish them, or else their appetites were still greedy after more of the same kind: or this may respect a famine, either at the siege of Samaria, or in their captivity; when they who had lived so voluptuously should have so little to eat, that it should not satisfy them: or though, as others, they eat to the honour of their idols, expecting to be blessed with plenty by them, they shall not have it: they shall commit whoredom, and shall not increase;
that is, their offspring; they shall not beget children, so the Targum, Jarchi, and Kimchi; or the children they beget shall quickly die; yea, though they commit whoredom in the idol's temple with that view, where the women prostituted themselves for that purpose: because they have left off to take heed to the Lord;
to his word, and worship, and ordinances, which they formerly had some regard unto, but now had relinquished: or, "the Lord they have forsaken", or "left off to observe" F25; his ways, his word, and worship. R. Saadiah connects this with the following words, they have forsaken the Lord to observe fornication and wine; but wrongly.
