Exodus 7:8-10

⁸ Yahweh spoke to Moses and to Aaron, saying, ⁹ “When Pharaoh speaks to you, saying, ‘Perform a miracle!’ then you shall tell Aaron, ‘Take your rod, and cast it down before Pharaoh, and it will become a serpent.’”

¹⁰ Moses and Aaron went in to Pharaoh, and they did so, as Yahweh had commanded. Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
