'Keeper' in the Bible

You Beth-lehem, in the land of Judah, are not the least among the chiefs of Judah: out of you will come a ruler, who will be the keeper of my people Israel.

But when he saw all the people he was moved with pity for them, because they were troubled and wandering like sheep without a keeper.

And before him all the nations will come together; and they will be parted one from another, as the sheep are parted from the goats by the keeper.

Then said Jesus to them, All of you will be turned away from me this night: for it is said in the Writings, I will put to death the keeper of the sheep, and the sheep of the flock will be put to flight.
