'Food' in the Bible

Thus saith the Lord Jehovah: Behold, I am against the shepherds; and I will require my sheep at their hand, and cause them to cease from feeding the flock: that the shepherds may feed themselves no more; and I will deliver my sheep from their mouth, that they may not be food for them.

And by the river, upon its bank, on the one side and on the other, shall grow all trees for food, whose leaf shall not fade, nor their fruit fail: it shall bring forth new fruit every month, for its waters issue out of the sanctuary; and the fruit thereof shall be for food, and the leaf thereof for medicine.
