Jeremiah 36:31
Here a reason is given for what the former verse contains; for if the Prophet had only said, that the dead body of the king would remain unburied and cast out in dishonor to be exposed in the night to the cold and in the day to the heat, the narrative would not have produced the effect intended; but God shews here the cause, which was this, that he had forewarned King Jehoiakim and all his counsellors, (called here servants) and the inhabitants of Jerusalem, and all the Jews universally: as then they had been in due time clearly told what calamity was near at hand, and yet no one had repented, for this so great an obstinacy God says now that he would take vengeance, I will visit him and his seed and the whole people for their iniquity — what was the iniquity? even that they had so grievously and in so many ways provoked God, and had not returned to a sound mind, though reproved by the Prophet, but had become more and more hardened.
