Exodus 4:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ And he said, ‘Throw it on the ground.’ So he threw the staff on the ground, and it became a snake; and Moses drew back from it. ⁴ Then the Lord said to Moses, ‘Reach out your hand, and seize it by the tail’—so he reached out his hand and grasped it, and it became a staff in his hand— ⁵ ‘so that they may believe that the Lord, the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.’
