Shmuel Alef 1:4-6

Orthodox Jewish Bible

⁴ And when the time was that Elkanah offered sacrifice, he gave to Peninnah his wife, and to all her banim and her banot, portions;

⁵ But unto Channah he gave a double portion; for he loved Channah; but Hashem had shut up her womb.

⁶ And her tzarah (adversary) also provoked her greatly, for to make her fret, because Hashem had shut up her womb.
