'Drove' in the Bible

So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.

And when the fowls came down upon the carcases, Abram drove them away.

And he delivered them into the hand of his servants, every drove by themselves; and said unto his servants, Pass over before me, and put a space betwixt drove and drove.

And he said, What meanest thou by all this drove which I met? And he said, These are to find grace in the sight of my lord.
