And the LORD said unto Moses, "Put forth thine hand and take it by the tail." And he put forth his hand and caught it, and it became a rod again in his hand.

And the LORD said furthermore unto him, "Thrust thine hand into thy bosom." And he thrust his hand into his bosom and took it out. And behold, his hand was leprous, even as snow.

And he said, "Put thine hand into thy bosom again." And he put his hand into his bosom again, and plucked it out of his bosom, and behold, it was turned again as his other flesh.

Then the LORD said unto Moses, "Now shalt thou see what I will do unto Pharaoh, for with a mighty hand shall he let them go, and with a mighty hand shall he drive them out of his land."
