Charles Ellicott Commentary Leviticus 22:6

"the soul that toucheth any such shall be unclean until the even, and shall not eat of the holy things, unless he bathe his flesh in water." — Leviticus 22:6 (ASV)

The soul that has touched. —Better, the man who has, that is, the priest for whom these laws are here enacted. Hence, the ancient Chaldee version renders it “the man a priest.”

Shall be unclean until evening. —When the day ends and another begins , and when he had to immerse his body in water.
