'Pray for' in the Bible

And Moses will say to Pharaoh, Be honored over me: at what time shall I pray for thee and for thy servants and for thy people, to cut off the frogs from thee and from thy houses, only in the river shall they remain?

And Pharaoh will say, I will send you forth and sacrifice ye to Jehovah your God in the desert; only departing, ye shall not go far away: 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.
