Here, I. The people of Israel are charged with spiritual adultery: O Israel! thou hast gone a whoring from thy God, v. 1. Their covenant with God was a marriage-covenant, by which they were joined to him as their God, renouncing all others. But when they set up idols and worshipped them, when they fled to creatures for succour and put a confidence in them, they went a whoring from God as their God, and honoured the pretenders and rivals with the affection, adoration, and confidence, which were due to God only. Other people were idolaters, but that sin was not, in them, going a whoring from God, as it was in Israel that had been married to him. Note, The sins of those who have made a profession of religion and relation to God are more provoking to him than the sins of others. As a proof of their going a whoring from God, it is charged upon them that they loved a reward upon every corn-floor. 1. They loved to give rewards to their idols, in the offerings and first-fruits they presented to them out of every corn-floor. They took a strange pleasure in serving their idols with that which they would have grudged to consecrate to God and employ in his service. Note, It is common for those that are niggardly in the expenses of their religion to be very prodigal in spending upon their lusts. Or, 2. They loved to receive rewards from their idols; and such they reckoned the fruits of the earth to be: These are my rewards, which my lovers have given me, ch. ii. 12. Note, Those are directly disposed to spiritual idolatry that love a reward in the corn-floor better than a reward in the favour of God and eternal life.
