And for these ye shall be unclean. — Rather, and by these ye shall be defiled, that is, the beasts and animals specified in Leviticus 11:26-27.
Shall be unclean until the even. — For coming in contact with the dead body of the animals contracts defilement for the rest of the day, and till the beginning of a new day, which took place after sunset (comp. Leviticus 23:32). During these hours of legal uncleanness he was not allowed to enter the sanctuary, touch any sacred thing, or have intercourse with those who were legally clean, since contact with one who has contracted legal defilement imparted defilement to both persons and things.
