English: “And you shall take for yourself” — he may not take two women, one for himself and one for his father, or one for himself and one for his son.
On the daf / in context: The extra word “lecha” restricts the permission to the soldier himself. The Gemara (and Rambam, Melachim 8:3) therefore forbids using the captive-woman procedure to acquire a wife for one’s father or son at the same time.
Type of Learning
Mi’ut from the word “lecha.”
What Is Learned
The captive-woman permission is personal: a soldier may take her only for himself, not simultaneously for his father or son.
