Jeremiah 19:8

"And I will make this city an astonishment, and a hissing; everyone that passeth thereby shall be astonished and hiss because of all the plagues thereof. And I will cause them to eat the flesh of their sons and the flesh of their daughters; and they shall eat everyone the flesh of his friend, in the siege and in the distress, wherewith their enemies, and they that seek their life, shall distress them."

This terrible warning is an almost verbatim quotation from Deuteronomy 28:53, in which the Great Lawgiver Moses had warned Israel of their fate IF they should give up serving their true God. Israel had indeed defaulted in that very act of disobedience; and now Jeremiah warned that the Mosaic penalty would be enforced.

Did such an awful thing actually happen? Alas, the answer must be that it did. (1) In the siege of Samaria that led to the fall of the Northern kingdom in 722 B.C. (2 Kings 6:26ff);[18] (2) again in 586 B.C. in the Babylonian invasion by Nebuchadnezzar; and (3) also in A.D. 70 preceding the total destruction of Jerusalem by Vespasian and Titus. The Biblical confirmation of these sad episodes is found in Lamentations 2:20; 4:10; 2 Kings 6:28-29; and the historical record of Josephus confirms that in 70 A.D.[19]
