(I Samuel 1:1-2)
1 Now there was a certain man of Ramathaim Zophim, of the mountains 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.
2 And he had two wives: the name of one was Hannah, and the name of the other Peninnah. Peninnah had children, but Hannah had no children.

(I Samuel 1:10)
10 And she was in bitterness of soul, and prayed to the LORD and wept in anguish.

(I Samuel 1:20)
20 So it came to pass in the process of time that Hannah conceived and bore a son, and called his name Samuel, saying, "Because I have asked for him from the LORD."

(I Samuel 1:24-28)
24 Now when she had weaned him, she took him up with her, with three bulls, one ephah of flour, and a skin of wine, and brought him to the house of the LORD in Shiloh. And the child was young.
25 Then they slaughtered a bull, and brought the child to Eli.
26 And she said, "O my lord! As your soul lives, my lord, I am the woman who stood by you here, praying to the LORD.
27 "For this child I prayed, and the LORD has granted me my petition which I asked of Him.
28 "Therefore I also have lent him to the LORD; as long as he lives he shall be lent to the LORD." So they worshiped the LORD there.
