Exodus 4:8 VOICE

[8] Eternal One: If they refuse to believe you, and are not persuaded after you perform the first sign, perhaps they will be after the second sign. But if they refuse to believe you and are not persuaded after you perform the first two signs, then here is a third sign: Take some water from the Nile and pour it out onto the ground. The water you take from the Nile will become blood on the ground.
