⁸ And all these thy servants shall come down to me, and shall worship me, saying: Go forth thou, and all the people that is under thee: after that we will go out.

⁹ And he went out from Pharao exceeding angry. But the Lord said to Moses: Pharao will not hear you, that many signs may be done in the land of Egypt.
