Parashas Acharei Mos · Passuk 17:07
Chabad.org — English translation + Rashi
Torah Temima points to Zevachim 106b.
English: One might think that an animal consecrated while bamot were permitted and later offered outside after the ban incurs karet; “this shall be an everlasting statute for them” limits the penalty to the cases already stated.
Limit of karet for transitional consecrations
Karet for offering outside does not automatically extend to every animal consecrated under the earlier lenient regime.
