Jeremiah 21:11

In short, the Prophet intimates that God’s wrath might be alleviated, though not wholly pacified, provided the king and his counsellors began to act rightly and justly. But he mentions the house of David, not for honor’s sake, but, on the contrary, by way of reproach; nor does he refer to David, as some unmeaningly assert, because he ruled justly and was a most excellent and upright king; but the Prophet had regard to God’s covenant. For we know that they deceived themselves when they thought that they were to be exempt from trouble through a peculiar privilege, because God had chosen that family, and promised that the kingdom would be perpetual. Thus hypocrites appropriate to their own advantage whatever God has promised; and at the same time they boast, though without faith and repentance, that God is bound to them. Such, then, was the presumption of the king and his counsellors; for they who were David’s descendants doubted not but that they were exempt from the common lot of men, and that they were, as they say, sacred beings. Hence the Prophet says, in contempt, The house of David! that is, “let these vain boastings now cease, for God will not spare you, though you may a hundred times boast that you are the descendants of David.” And at the same time he upbraids them with having become wholly degenerate, for God had made a covenant with David on the condition that he served him faithfully; but his posterity were become perfidious and apostates. Therefore the Prophet brought before them the name of David, in order that he might the more reproach them, because they were become wholly unlike their father, having departed from his piety.
