Exodus 4:7-9

Young's Literal Translation

⁷ and He saith, `Put back thy hand unto thy bosom;' and he putteth back his hand unto his bosom, and he bringeth it out from his bosom, and lo, it hath turned back as his flesh --

⁸ `-- and it hath come to pass, if they do not give credence to thee, and hearken not to the voice of the first sign, that they have given credence to the voice of the latter sign.

⁹ `And it hath come to pass, if they do not give credence even to these two signs, nor hearken to thy voice, that thou hast taken of the waters of the River, and hast poured on the dry land, and the waters which thou takest from the River have been, yea, they have become -- blood on the dry land.'
