6 Moses and Aaron did what the Lord commanded.
7 At the time when they spoke to the king, Moses was eighty years old, and Aaron was 83.
8 The Lord said to Moses and Aaron,
9 “If the king demands that you prove yourselves by performing a miracle, tell Aaron to take his stick and throw it down in front of the king, and it will turn into a snake.”
10 So Moses and Aaron went to the king and did as the Lord had commanded. Aaron threw his stick down in front of the king and his officers, and it turned into a snake.
11 Then the king called for his wise men and magicians, and by their magic they did the same thing.
