'Of the Flesh' in the Bible

And there shall be no leavened bread seen with you in all your territory seven days; neither shall there any part of the flesh, which you sacrificed the first day at evening, remain all night until the morning.

So that he will not give to any of them of the flesh of his children whom he shall eat: because he has nothing left him in the siege, and in the distress with which your enemies shall distress you in all your gates.
