'Pray' in the Bible

Then Pharaoh summoned Moses and Aaron and said, "Pray to the Lord that he may take the frogs away from me and my people, and I will release the people that they may sacrifice to the Lord."

Moses said to Pharaoh, "You may have the honor over me -- when shall I pray for you, your servants, and your people, for the frogs to be removed from you and your houses, so that they will be left only in the Nile?"

Pharaoh said, "I will release you so that you may sacrifice to the Lord your God in the desert. Only you must not go very far. Do pray for me."

Moses said, "I am going to go out from you and pray to the Lord, and the swarms of flies will go away from Pharaoh, from his servants, and from his people tomorrow. Only do not let Pharaoh deal falsely again by not releasing the people to sacrifice to the Lord."

Pray to the Lord, for the mighty thunderings and hail are too much! I will release you and you will stay no longer."

So now, forgive my sin this time only, and pray to the Lord your God that he would only take this death away from me."
