Exodus 4:1-3

New Revised Standard Version, Anglicised Catholic Edition

Moses’ Miraculous Power

4 Then Moses answered, ‘But suppose they do not believe me or listen to me, but say, “The Lord did not appear to you.”’ ² The Lord said to him, ‘What is that in your hand?’ He said, ‘A staff.’ 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.
