Midrasz do Rodzaju 35:24

“He seats the barren woman of the house as a happy mother of children. Hallelujah!” (Psalms 113:9) There are seven barren women: Sarah, Rivka, Rachel and Leah, Manoach’s wife, Chana and Zion…Another explanation. ‘He seats the barren woman’ this refers to Zion. “Sing you barren woman who has not borne…” (Isaiah 54:1) ‘a happy mother of children,’ “And you shall say to yourself, Who begot these for me…” (Isaiah 49:21)
