1 Samuel 1:3-5

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.
