Numbers 12:9-11

American Standard Version

⁹ And the anger of Jehovah was kindled against them; and he departed. ¹⁰ And the cloud removed from over the Tent; and, behold, Miriam was leprous, as white as snow: and Aaron looked upon Miriam, and, behold, she was leprous. ¹¹ And Aaron said unto Moses, Oh, my lord, lay not, I pray thee, sin upon us, for that we have done foolishly, and for that we have sinned.
