1 Samuel 1:4-6

4 When the day came for Elkanah to offer sacrifice, he used to give portions to his wife Peninnah and to all her sons and daughters,

5 but he would give a double portion to Hannah because he loved her, though the Lord had closed her womb. [AC]

6 Her rival, [1] to upset her, would torment her constantly, since the Lord had closed her womb. [AD]
