Exodus 29:30

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 shall the son who is priest in his place put them on, when he comes into the tent of meeting to minister in the holy place.

Seven days shall the son that is priest in his stead put them on, when he cometh into the tent of meeting to minister in the holy place.

seven days doth the priest in his stead (of his sons) put them on, when he goeth in unto the tent of meeting, to minister in the sanctuary.

The son who succeeds him as priest and enters the Tent of Meeting to minister in the Holy Place must wear them for seven days.
