John Gill Commentary Leviticus 11:25

"And whosoever beareth [aught] of the carcass of them shall wash his clothes, and be unclean until the even." — Leviticus 11:25 (ASV)

And whosoever beareth [ought] of the carcass of them
That carries them from one place to another, out of the camp, city, village, or house or field where they may lie; and though this is done with a good design, as being offensive or infectious, yet such an one

shall wash his clothes, and be unclean until the even ;
from which both Jarchi and Aben Ezra infer, that the pollution by hearing or carrying is greater than that by touching; since such a man, so defiled, was obliged to wash his clothes as well as his body; so saints, that have contracted pollution by any manner of sin, are to wash their garments and make them white in the blood of the Lamb, (Revelation 7:14) .
