Midras Yesaya 66:9: Aggadat Bereshit

Chapter 29: Prophets [1] "For the LORD had closed Hannah's womb." (1 Samuel 2:21) This refers to the statement "I will not cause pain nor create children" (Isaiah 66:9), which is talking about Hannah, as it is said "And unto Hannah he gave a worthy portion; for he loved Hannah, but the LORD had shut up her womb." (1 Samuel 1:5) "[If I am the one who gives birth and stops it]" (Isaiah, same verse). If I am the one who gives birth to Sarah and stops it for Abimelech's household, [as it says] "for he had closed up every womb" (Genesis 20:18). Another interpretation is that if I am the one who gives birth to Israel, as it says "who are born from me" (Isaiah 46:3), and I stop it for the enemy, as it says "all the nations are as nothing before Him" (Isaiah 40:17), for it is written "I will cut off from Babylon name and remnant, descendants and posterity, declares the Lord" (Isaiah 14:22). "This name is her currency. She'ar (remnant) will not be a survivor, etc." (Obadiah 1:18), "And the son (nephew) represents the kingdom, and the grandson represents the general. Alternatively, if I give birth to Zion, as it says, "For Zion has gone into labor and has given birth to her children" (Isaiah 66:8)." "And Atzeret (עצרתי) refers to Sodom. Its inhabitants will also die like that (ימותון - will die) (Isaiah 1:9). This is Sodom, as it says, "These are the sons of Seir the Horite [the inhabitants of the land]" (Genesis 36:20). But for Israel, "my salvation will be forever" (Isaiah 51:6)."
