Leviticus 6:9-11

Young's Literal Translation

⁹ `Command Aaron and his sons, saying, This [is] a law of the burnt-offering (it [is] the burnt-offering, because of the burning on the altar all the night unto the morning, and the fire of the altar is burning on it,)

¹⁰ that the priest hath put on his long robe of fine linen, and his fine linen trousers he doth put on his flesh, and hath lifted up the ashes which the fire consumeth with the burnt-offering on the altar, and hath put them near the altar;

¹¹ and he hath stripped off his garments, and hath put on other garments, and hath brought out the ashes unto the outside of the camp, unto a clean place.
