'Entreat the Lord' in the Bible

Then Pharaoh called for Moses and Aaron and said, “Entreat the Lord that He remove the frogs from me and from my people; and I will let the people go, that they may sacrifice to the Lord.”

The king said to the man of God, “Please entreat the Lord your God, and pray for me, that my hand may be restored to me.” So the man of God entreated the Lord, and the king’s hand was restored to him, and it became as it was before.

But if they are prophets, and if the word of the Lord is with them, let them now entreat the Lord of hosts that the vessels which are left in the house of the Lord, in the house of the king of Judah and in Jerusalem may not go to Babylon.
