1 Samuel 1:4-7

1:4 Whenever the day came for Elkanah to sacrifice, he used to give meat portions to his wife Peninnah and to all her sons and daughters. 1:5 But he would give a double portion to Hannah, because he especially loved her. Now the Lord had not enabled her to have children. 1:6 Her rival wife used to upset her and make her worry, for the Lord had not enabled her to have children. 1:7 Peninnah 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.
