'Pray for' in the Bible

And Moses said unto Pharaoh, "Appoint thou the time unto me, when I shall pray for thee and thy servants and thy people, to drive away the frogs from thee and thy house, so that they shall remain but in the river only."

And Pharaoh said, "I will let you go, that ye may sacrifice unto the LORD your God in the wilderness: only go not far away, and see that ye pray for me."
