Deuteronomy 28:52-53

52And he shall besiege thee in all thy gates, until thy high and strong walls wherein thou trustedst come down, throughout all thy land; and he shall besiege thee in all thy gates in all thy land, which Jehovah thy 1God hath given thee.

53And in the siege, and in the straitness, wherewith thine enemies shall distress thee, thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters whom Jehovah thy 2God hath given thee.
