1 Samuel 1:1-6

Now there was a certain man from Ramathaim-zophim from the hill country 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. He had two wives: the name of one was Hannah and the name of the other Peninnah; and Peninnah had children, but Hannah had no children. Now this man would go up from his city yearly to worship and to sacrifice to the LORD of hosts in Shiloh. And the two sons of Eli, Hophni and Phinehas, were priests to the LORD there. When the day came that Elkanah sacrificed, he would give portions to Peninnah his wife and to all her sons and her daughters; but to Hannah he would give a double portion, for he loved Hannah, but the LORD had closed her womb. Her rival, however, would provoke her bitterly to irritate her, because the LORD had closed her womb.
