Exodus 4:4-6

Revised Standard Version Catholic Edition

⁴ But the Lord said to Moses, “Put out your hand, and take it by the tail”—so he put out his hand and caught 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, has appeared to you.” ⁶ Again, the Lord said to him, “Put your hand into your bosom.” And he put his hand into his bosom; and when he took it out, behold, his hand was leprous, as white as snow.
