God spoke to Moshe, saying: Command Aaron and his sons, saying: This is the law of the burnt-offering.

It is the burnt-offering that remains on the pyre on the altar throughout the night until the morning, and the fire of the altar shall be kept burning on it.

The kohen shall put on his linen tunic and shall wear linen breeches on his flesh.

He shall lift up [a pan-full of] the ashes that were produced when the fire consumed the burnt-offering on the altar and place them next to the altar.

Then he shall remove his garments, put on other garments, and take out [other] ashes beyond the camp to a pure place.

The fire on the altar shall be kept burning on it; it must not be extinguished.

The kohen shall burn wood upon it, morning after morning.

He shall arrange the burnt-offering upon it and burn the fat of the peace-offerings upon it.

A constant fire shall be kept burning on the altar; it must not be extinguished.”
