Jeremiah 51:5

For Israel hath not been forsaken nor Judah of his God, of the Lord of hosts, the chosen people of Jehovah being still in His care, under His gracious protection; though their land was filled with sin against the Holy One of Israel, rather, "but the land of the Chaldeans is filled with guilt," because they refused to accept the true God in spite of the many manifestations of His power and glory in their midst as brought to their attention, for instance, through Daniel and his friends. Therefore the Lord addresses Himself to the members of His chosen people living in Babylon, urging the proper behavior at the time of Babylon's downfall.
