'Feed' in the Bible

Open your doors, O Lebanon,That a fire may feed on your cedars.

Thus saith the LORD my God; Feed the flock of the slaughter;

And I will feed the flock of slaughter, even you, O poor of the flock. And I took unto me two staves; the one I called Beauty, and the other I called Bands; and I fed the flock.

Then said I, I will not feed you: that that dieth, let it die; and that that is to be cut off, let it be cut off; and let the rest eat every one the flesh of another.

For, lo, I will raise up a shepherd in the land, which shall not visit those that be cut off, neither shall seek the young one, nor heal that that is broken, nor feed that that standeth still: but he shall eat the flesh of the fat, and tear their claws in pieces.
