Charles Ellicott Commentary Leviticus 15:7

"And he that toucheth the flesh of him that hath the issue shall wash his clothes, and bathe himself in water, and be unclean until the even." — Leviticus 15:7 (ASV)

And he that toucheth the flesh. — With such intense loathing was the person regarded who had contracted this infirmity, that even the physician who had to examine him professionally became defiled for the rest of the day. He had to wash his clothes and immerse his entire body in water before he could be permitted to enjoy his sacred privileges.
