Leviticus 22:5 or if a man touches any teeming things by which he is made unclean, or any man by whom he is made unclean, whatever his uncleanness;

Leviticus 22:6 a person who touches any such shall be unclean until evening, and shall not eat of the holy gifts unless he has bathed his body in water. (NASB ©1995)
