出埃及记 7:20

摩西、亚伦就照耶和华所吩咐的行。亚伦在法老和臣仆眼前举杖击打河里的水，河里的水都变作血了。

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.
