8The LORD said to Moses and Aaron:9When Pharaoh says to you, "Give us a sign," then you shall say to Aaron, "Take your staff and throw it before Pharaoh; it shall become a tannin."10Moses and Aaron went to Pharaoh and did just as the LORD had commanded. Aaron threw his staff down in front of Pharaoh and his servants, and it became a tannin.11Pharaoh also called for the wise men and the sorcerers, and the magicians of Egypt did the same things with their secret spells.12Each man threw down his staff, and they became tanninim, and Aaron's staff swallowed their staffs.13Pharaoh's heart was strengthened, and he did not listen to them, just as the LORD had said.
