1 Samuel 1:4-7

When the day came that Elkanah sacrificed, he would give portions [of the sacrificial meat] to Peninnah his wife and all her sons and daughters. But to Hannah he would give a double portion, because he loved Hannah, but the LORD had given her no children. Hannah’s rival provoked her bitterly, to irritate and embarrass her, because the LORD had left her childless. So it happened year after year, whenever she went up to the house of the LORD, Peninnah provoked her; so she wept and would not eat.
