Księga Wyjścia 7:20

Mojżesz i Aaron uczynili tak, jak PAN rozkazał. Aaron podniósł laskę i uderzył wody rzeki na oczach faraona i jego sług. I wszystkie wody rzeki zamieniły się w krew.

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.
