Exodus 4:2-5

2The Lord said to him, “What is that in your hand?” And he said, “1A staff.” 3Then He said, “Throw it on the ground.” So he threw it on the ground, and 2it turned into a serpent; and Moses fled from it. 4But the Lord said to Moses, “Reach out with your hand and grasp it by its tail”--so he reached out with his hand and caught it, and it turned into a staff in his 3hand-- 5“so that 4they may believe that 5the Lord, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”
