Exodus 4:1-3

New King James Version

Miraculous Signs for Pharaoh

4 Then Moses answered and said, “But suppose they will not believe me or listen to my voice; suppose they say, ‘The Lord has not appeared to you.’ ”

² So the Lord said to him, “What is that in your hand?”

He said, “A rod.”

³ And He said, “Cast it on the ground.” So he cast it on the ground, and it became a serpent; and Moses fled from it.
