English: “From the turtledoves” — “from” excludes one that was cohabited with and one that was worshiped.
In the sugya: The partitive “min” before “ha-torim” functions as a miyut. Birds that have been the object of bestiality or of idolatrous worship are excluded from the eligible pool.
Type of Learning
Miyut from “min” before the species name — excluding nirba and ne’evad.
What Is Learned
A bird that was used for bestiality or that was worshiped as an idol is unfit as an olah. The verse’s “from the turtledoves” selects only pure specimens; those two categories of prior use permanently disqualify the bird.
