English: “Completely closed up.” Why these two expressions of closing? Rabbi Elazar said: One for the man—seminal emission—and two for the woman—seminal emission and childbirth.
On the daf / in context: The doubled verb is parsed as covering both male and female reproductive functions that were halted in Avimelech’s household.
Type of Learning
Derash on the verse (Bavli sugya) — not a formal named middah of the 13. A doubled verb is distributed across the sexes and their respective functions.
What Is Learned
The double language “atzor atzar” indicates that both the men (emission) and the women (emission and birth) of Avimelech’s house were closed.
