Charles Ellicott Commentary Deuteronomy 28:53

"And thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters, whom Jehovah thy God hath given thee, in the siege and in the distress wherewith thine enemies shall distress thee." — Deuteronomy 28:53 (ASV)

Thou shalt eat the fruit of thine own body. —Specially confirmed in the siege of Samaria by the Syrians (2 Kings 6:26–29; but see on Deuteronomy 28:56), and also in Jerusalem when besieged by Nebuchadnezzar. (Lamentations 4:10.)
