1 Samuel 1:3-6

Now this man used to go up year by year from his city to worship and to sacrifice to the LORD of hosts at Shiloh, where the two sons of Eli, Hophni and Phinehas, were priests of the LORD. On the day when Elkanah sacrificed, he would give portions to Peninnah his wife and to all her sons and daughters. But to Hannah he gave a double portion, because he loved her, though the LORD had closed her womb. And her rival used to provoke her grievously to irritate her, because the LORD had closed her womb.
