Rambam In-Depth: Why an Invalid Maaser Beheima Can Still Become Holy

Welcome to Rambam In-Depth: Hilchos Bechoros, Perek 7, Halacha 5.

Can a tithe that doesn’t work still make something holy? The Rambam says yes — and his own novel ruling on Maaser Beheima explains exactly how.

The Rambam paskens that you cannot tithe animals born in one year to cover the obligation of another year — just as you can’t tithe old produce to cover new, or new produce to cover old. This is derived from a hekesh: the Torah compares the tithing of animals (Maaser Beheima) to the tithing of produce (Maaser Dagan), each of which must be done year by year, independently.

But the Rambam adds his own chiddush: if someone did tithe an animal from one year to cover another, b’dieved (after the fact), the tithing is valid — because of the chumra of kodshim. That’s surprising, because the same leniency does not apply to Maaser Dagan, where a cross-year tithe after the fact is invalid. So why is Maaser Beheima different?

The Sefer Shittah Mekubetzet on Pesachim resolves the contradiction with a novel idea: Maaser Beheima actually carries two separate dinim at once — the din of maaser (the tithing mechanism itself) and the din of kodshim (the sanctified status of the tenth animal, like a shelamim, a peace offering). Even when the maaser mechanism fails across years, the din of kodshim operates on its own and gives the animal its holy status regardless.
