And the Lord spake unto Moses and unto Aaron After he had given them their commission, and instructions to go to Pharaoh, and a little before they went in to him:
6
And Moses and Aaron did as the LORD commanded them, so did they.
7
And Moses was eighty years old and Aaron eighty-three years old when they spoke unto Pharaoh.
8
And the LORD spoke unto Moses and unto Aaron, saying,
9
If Pharaoh shall answer you, saying, Show a miracle, then thou shalt say unto Aaron, Take thy rod and cast it before Pharaoh, that it shall become a dragon.
10
So Moses and Aaron went in unto Pharaoh, and they did as the LORD had commanded; and Aaron cast down his rod before Pharaoh and before his slaves, and it became a dragon.
