Exodus 8:8-10

8Then Pharaoh called for Moses and Aaron, and said, Intreat Yhwh, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto Yhwh. 9And 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?123 10And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto Yhwh our God.4
