English: “And you see among the captives” — at the time of the capture itself.
On the daf / in context: The Gemara (Kiddushin 21b) and Sifrei require that the soldier’s eye fall on her at the moment she is taken captive. If he later decides to take a captive woman who was already in the camp for sale or service, the special permission does not apply.
Type of Learning
Derash on the verse (Bavli / Sifrei) — limiting the permission to the instant of capture by the force of “ba-shivyah.”
What Is Learned
The captive-woman permission is available only when the soldier notices her at the actual moment of capture, not later.
