“But,” objected Moses, “suppose they do not believe me or listen to me? For they may say, ‘The Lord did not appear to you.’”

The Lord said to him: What is in your hand? “A staff,” he answered.

God said: Throw it on the ground. So he threw it on the ground and it became a snake, and Moses backed away from it.

Then the Lord said to Moses: Now stretch out your hand and take hold of its tail. So he stretched out his hand and took hold of it, and it became a staff in his hand.

That is so they will believe that the Lord, the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, did appear to you.

Again the Lord said to him: Put your hand into the fold of your garment. So he put his hand into the fold of his garment, and when he drew it out, there was his hand covered with scales, like snowflakes.

Then God said: Put your hand back into the fold of your garment. So he put his hand back into the fold of his garment, and when he drew it out, there it was again like his own flesh.

If they do not believe you or pay attention to the message of the first sign, they should believe the message of the second sign.

And if they do not believe even these two signs and do not listen to you, take some water from the Nile and pour it on the dry land. The water you take from the Nile will become blood on the dry land.
