1 Samuel 1:4-7

4Whenever the day came for Elkanah to sacrifice, he used to give meat portions to his wife Peninnah and to all her sons and daughters.

5But he would give a double portion to Hannah, because he especially loved her. Now the Lord had not enabled her to have children.

6Her rival wife used to upset her and make her worry, for the Lord had not enabled her to have children.

7Peninnah would behave this way year after year. Whenever Hannah went up to the Lord’s house, Peninnah would upset her so that she would weep and refuse to eat.
