Exodus 8:8, 28

Then Pharaoh summoned Moses and Aaron and begged, “Plead with the LORD to take the frogs away from me and my people. I will let your people go, so they can offer sacrifices to the LORD.”

“All right, go ahead,” Pharaoh replied. “I will let you go into the wilderness to offer sacrifices to the LORD your God. But don’t go too far away. Now hurry and pray for me.”
