'Eat the Fruit' in the Bible

and shall eat the fruit of your livestock, and the fruit of your ground, until you are destroyed; that also shall not leave you grain, new wine, or oil, the increase of your livestock, or the young of your flock, until they have caused you to perish.

You shall eat the fruit of your own body, the flesh of your sons and of your daughters, whom Yahweh your God has given you, in the siege and in the distress with which your enemies shall distress you.
