'Pray for' in the Bible

And Moses said to Pharaoh, "{I leave to you the honor} over me. When shall I pray for you and for your servants and for your people to cut off the frogs from you and from your houses? They will be left only in the Nile."

And Pharaoh said, "I myself will release you, and you will sacrifice to Yahweh your God in the desert. Only surely you must not go far. Pray for me."

And Moses will say, Behold, I will go forth from thee, and pray for thee to Jehovah; and the gad-fly shall depart from Pharaoh, from his servants and from his people, to-morrow: only Pharaoh shall not add to deceive, not to send away the people to sacrifice to Jehovah.
