Exodus 8:11

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?

And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the LORD our God.

And Moses and Aaron went out from Pharaoh: and Moses cried unto the LORD because of the frogs which he had brought against Pharaoh.

And the LORD did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields.
