English: Might one who vows a bird not bring less than two birds? The verse says “and he shall bring it” — even a single bird.
In the sugya: A possible inference from the plural species names is that a vow of “a bird” requires a pair. The singular “ve-hikrivo” overrides that inference and permits a single bird to fulfill the vow.
Type of Learning
Miyut of a pair requirement from the singular “ve-hikrivo.”
What Is Learned
A vowed bird olah may be fulfilled with one bird. The verse’s singular language teaches that the volunteer is not required to bring a pair; a single valid bird satisfies the nedavah.
