Exodus 8:9

And the Lord did as Moses said, and the frogs died out of the houses, and out of the villages, and out of the fields.

And Moses said unto Pharaoh, Glory over me: when shall I intreat for thee, and for thy servants, and for thy people, to destroy the frogs from thee and thy houses, that they may remain in the river only?

Moses said to Pharaoh, “I give you the honor of setting the time that I should pray for you, and for your servants, and for your people, that the frogs be destroyed from you and your houses, and remain in the river only.”
