So Mosheh and Aharon went in to Pharaoh, and they did so, as יהוה commanded. And Aharon threw his rod before Pharaoh and before his servants, and it became a serpent.
“Go to Pharaoh in the morning, as he goes out to the water, and you shall stand by the river’s bank to meet him. And take in your hand the rod which was turned into a serpent.
And Mosheh and Aharon did so, as יהוה commanded. And he lifted up the rod and struck the waters that were in the river, in the eyes of Pharaoh and in the eyes of his servants. And all the waters that were in the river were turned to blood.
When Pharaoh speaks to you, saying, ‘Show a miracle for yourselves,’ then you shall say to Aharon, ‘Take your rod and throw it before Pharaoh, and let it become a serpent.’
“And if they hide themselves on top of Karmel, from there I shall search, and take them. And if they hide from before My eyes at the bottom of the sea, from there I shall command the serpent, and it shall bite them.
they shall take up snakes, and if they drink any deadly drink it shall by no means hurt them, they shall lay hands on the sick and they shall get well.”
