And you shall bring there your burnt-offerings and your sacrifices, and your tithes and the contribution of your hand, and your vows and your freewill-offerings, and the firstborn of your herd and of your flock.
English: “And the firstborn of your herd and of your flock” — to include the animal of partners, which is subject to the law of the firstborn.
On the daf / in context: Even though a later verse uses singular language, the plural form here brings partnership animals of Israelites into the obligation of bechorah (while a non-Jewish partner is excluded elsewhere).
Type of Learning
Derash on the verse (Sifrei / Bavli) — extending bechorah to jointly owned animals.
What Is Learned
An animal owned in partnership by Israelites is subject to the firstborn laws.
