Exodus 7:20

Moses en Aäron deden, wat Jahweh hun bevolen had. Hij hief zijn staf op, sloeg ten aanschouwen van Farao en zijn hof op het water van de Nijl, en al het water van de Nijl werd in bloed veranderd.

And Moses and Aaron did so, as the LORD commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood.
