'Pray' in the Bible

Then Pharaoh said, "I'll let you go so you can offer sacrifices to the LORD your God in the desert. But you must not go very far away. Pray for me."

Moses said, "Right now I'm going to leave you, and I'll pray to the LORD that the swarms of insects may depart from Pharaoh, from his officials, and from his people tomorrow. But Pharaoh, don't continue lying by not letting the people go to offer sacrifices to the LORD."

Pray to the LORD! There has been enough of God's thunder and hail! I'll let you go, and you need not stay any longer."

Now, please forgive my sin only this time, and pray to the LORD your God that he would at least remove this from me."
