Exodus 4:8-9

Christian Standard Bible

⁸ “If they will not believe you and will not respond to the evidence of the first sign, they may believe the evidence of the second sign. ⁹ And if they don’t believe even these two signs or listen to what you say, take some water from the Nile and pour it on the dry ground. The water you take from the Nile will become blood on the ground.”^(A)
