Verse 39. Thus were they defiled with their own works, and went a whoring with their own inventions. Not only the land but the inhabitants of it were polluted. They broke the marriage bond between them and the Lord, and fell into spiritual adultery. The language is strong, but the offence could not be fitly described in less forcible words. As a husband is deeply dishonoured and sorely wounded should his wife become unchaste and run riot with many paramours in his own house, so was the Lord incensed at his people for setting up gods many and lords many in his own land. They made and invented new gods, and then worshipped what they had made. What a folly! Their novel deities were loathsome monsters and cruel demons, and yet they paid them homage. What wickedness! And to commit this folly and wickedness they cast off the true God, whose miracles they had seen, and whose people they were. This was provocation of the severest sort.
