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 became a serpent; and Moses fled from it. 4But the Lord said to Moses, “Stretch out your hand and grasp it by its tail”--so he stretched out his hand and caught it, and it became a staff in his 3hand-- 5“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.”
