Jamieson, Fausset and Brown on Deuteronomy 28:53-57

53-57. And thou shalt eat the fruit of thine own body--(See 2Ki 6:29; La 4:10). Such were the dreadful extremities to which the inhabitants during the siege were reduced that many women sustained a wretched existence by eating the flesh of their own children. Parental affection was extinguished, and the nearest relatives were jealously, avoided, lest they should discover and demand a share of the revolting viands.
