And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place.
Seven days thou shalt make an atonement for the altar, and sanctify it; and it shall be an altar most holy: whatsoever toucheth the altar shall be holy.
Seven days shalt thou prepare every day a goat for a sin offering: they shall also prepare a young bullock, and a ram out of the flock, without blemish.
