6. And Moses and Aaron did so, as the Lord commanded them.
7. Now Moses was 80 years old and Aaron 83 years old when they spoke to Pharaoh.
8. And the Lord said to Moses and Aaron,
9. When Pharaoh says to you, Prove [your authority] by a miracle, then tell Aaron, Throw your rod down before Pharaoh, that it may become a serpent.
10. So Moses and Aaron went to Pharaoh and did as the Lord had commanded; Aaron threw down his rod before Pharaoh and his servants, and it became a serpent.
11. Then Pharaoh called for the wise men [skilled in magic and divination] and the sorcerers (wizards and jugglers). And they also, these magicians of Egypt, did similar things with their enchantments and secret arts.
