Exodus 4:3-5

JPS_ASV_Byz(i) 3 And He said: 'Cast it on the ground.' And he cast it on the ground, and it became a serpent; and Moses fled from before it. 4 And the LORD said unto Moses: 'Put forth thy hand, and take it by the tail - and he put forth his hand, and laid hold of it, and it became a rod in his hand - 5 that they may believe that the LORD, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee.'
