I Samuel 1:1-6

Now there was a certain man of Ramathaim Zophim, of the mountains of Ephraim, and his name was Elkanah the son of Jeroham, the son of Elihu, the son of Tohu, the son of Zuph, an Ephraimite. And he had two wives: the name of one was Hannah, and the name of the other Peninnah. Peninnah had children, but Hannah had no children. This man went up from his city yearly to worship and sacrifice to the LORD of hosts in Shiloh. Also the two sons of Eli, Hophni and Phinehas, the priests of the LORD, were there. And whenever the time came for Elkanah to make an offering, he would give portions to Peninnah his wife and to all her sons and daughters. But to Hannah he would give a double portion, for he loved Hannah, although the LORD had closed her womb. And her rival also provoked her severely, to make her miserable, because the LORD had closed her womb.
