Shemot 4:7-9

Orthodox Jewish Bible

⁷ And He said, Put thine yad into thy kheyk again. And he put his yad into his kheyk again; and plucked it out of his kheyk, and, hinei, it was turned again as his other basar.

⁸ And it shall come to pass, if they will not believe thee, neither pay heed to the voice of haOt Harishon, that they will believe the voice of haOt haAcharon.

⁹ And it shall come to pass, if they will not believe also these two otot, neither pay heed unto thy voice, that thou shalt take of the mayim of the Nile, and pour it upon the yabashah (dry land); and the mayim which thou takest out of the Nile shall become dahm upon the yabashah.
