Sefaria — Exodus 29:12
Sefaria — Zevachim 62a
E-Daf — Zevachim 62a
English: A baraita teaches that the horns of the altar are indispensable. Rav Huna derives this from the wording “the altar”: wherever Scripture says “the altar” in this context, the complete prescribed form is required.
On the daf / in context: See the cited source for the full section.
Derash on the verse.
The altar’s horns are not merely decorative; their presence is an indispensable part of the valid altar.
