Numbers 12:9-13

⁹And the anger of the Lord was kindled against them, and he went away.

¹⁰And the cloud departed from off the tabernacle; and, behold, Miriam became leprous, white as snow; and Aaron turned toward Miriam, and, behold, she was leprous.

¹¹Then said Aaron unto Moses, Alas, my Lord, do not, I beseech thee, account to us as sin that wherein we have done foolishly, and wherein we have sinned.

¹²Let her not be as a dead-born child, of which half the flesh is consumed, when it cometh out of its mother's womb.

¹³And Moses cried unto the Lord, saying, O God! do thou heal her, I beseech thee.
