出埃及記 7:20

摩西、亞倫就照耶和華所吩咐的行。亞倫在法老和臣僕眼前舉杖擊打河裏的水，河裏的水都變作血了。

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.
