Exodus 4:7-9

Douay-Rheims 1899 American Edition

⁷ And he said: Put back thy hand into thy bosom. He put it back, and brought it out again, and it was like the other flesh.

⁸ If they will not believe thee, saith he, nor hear the voice of the former sign, they will believe the word of the latter sign.

⁹ But if they will not even believe these two signs, nor hear thy voice: take of the river water, and pour it out upon the dry land, and whatsoever thou drawest out of the river shall be turned into blood.
