Tanaj sobre Levítico 1:7

And Adonoy spoke to Moshe, saying:

Command Aharon and his sons, saying; this is the law of the burnt-offering. It is the burnt-offering [which remains] on its pyre on the altar all night, until the morning, and the fire of the altar will be kept burning on it.

The kohein shall dress in his linen garment and he shall wear linen pants on his [body] skin; and he shall separate the ashes when the fire consumes the burnt-offering on the altar and place it next to the altar.
