'Give Over' in the Bible

The Lord said to me, "Look! I have already begun to give over Sihon and his land to you. Start right now to take his land as your possession."

So the Lord our God did indeed give over to us King Og of Bashan and his whole army and we struck them down until not a single survivor was left.

And you shall consume all the peoples whom the Lord your God will give over to you; your eye shall not pity them, nor shall you serve their gods, for that would be a [deadly] trap to you.
