Exodus 7:8-10

Holman Christian Standard Bible

⁸ The Lord said to Moses and Aaron, ⁹ “When Pharaoh tells you, ‘Perform a miracle,’ tell Aaron, ‘Take your staff and throw it down before Pharaoh. It will become a serpent.’”^{(A) 10} So Moses and Aaron went in to Pharaoh and did just as the Lord had commanded. Aaron threw down his staff before Pharaoh and his officials, and it became a serpent.
