Exodus 8:10-15

10And he said, Against to-morrow. And he said, Be it according to thy word; that thou mayest know that there is none like unto Jehovah our God. 11And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only. 12And Moses and Aaron went out from Pharaoh: and Moses cried unto Jehovah concerning the frogs which he had brought upon Pharaoh. 13And Jehovah did according to the word of Moses; and the frogs died out of the houses, out of the courts, and out of the fields. 14And they gathered them together in heaps; and the land stank. 15But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not unto them, as Jehovah had spoken.
