For they shall eat, and not have enough: they shall commit whoredom, and shall not increase: because they have left off to take heed to the LORD.
For they shall eat, and not have enough - just retribution on those who "eat up (greedily) the sin of my people" (Hosea 4:8): insatiable desire is its own tormentor. What the greedy man eats does him no god. He has no enjoyment or benefit from what he has, from his ever craving for more (Micah 6:14; Haggai 1:6, "Ye eat, but ye have not enough; ye drink, but ye are not filled with drink").
They shall commit whoredom, and shall not increase - literally, break forth. used of giving birth to children (Genesis 28:14 margin: cf. Genesis 38:29, "How hast thou broken forth?-Pharaz"). Not only their wives, but their concubines, shall be barren. To be childless was considered a great calamity among the Jews. Literally; 'they have committed whoredom, and shall not increase.' The means they used for increase, begin unlawful means, failed, because not having God's blessing. Polygamy is against God's law, "They twain shall be one flesh," and therefore tends to depopulation.
