'Support' in the Bible

Pul king of Assyria invaded the land, and Menahem paid him a thousand talents of silver to gain his support and to solidify his control of the kingdom.

Now look, you must be trusting in Egypt, that splintered reed staff. If a man leans for support on it, it punctures his hand and wounds him. That is what Pharaoh king of Egypt does to all who trust in him.
