Exodus 8:8-10

8And Pharaoh called Moses and Aaron, and said, Intreat Jehovah, that he may take away the frogs from me and from my people; and I will let the people go, that they may sacrifice to Jehovah.

9And Moses said to Pharaoh, Glory over me, for what time shall I intreat for thee, and for thy bondmen, and for thy people, to cut off the frogs from thee and from thy houses; [so that] they shall remain in the river only?

10And he said, For to-morrow. And he said, Be it according to thy word; that thou mayest know that there is none like Jehovah our 1God.
