1 Samuel 1:21

18 “May your maidservant find favor with you,” said Hannah. Then she went on her way, and she began eating again, and her face was no longer downcast.

19 The next morning Elkanah and Hannah got up early to bow in worship before the LORD, and then returned home to Ramah. And Elkanah had relations with his wife Hannah, and the LORD remembered her.

20 So in the course of time, Hannah conceived and gave birth to a son. She named him Samuel, saying, “Because I have asked for him from the LORD.”

21 Then Elkanah and all his house went up to make the annual sacrifice to the LORD and to fulfill his vow,

22 but Hannah did not go. “After the boy is weaned,” she said to her husband, “I will take him to appear before the LORD and to stay there permanently.”

23 “Do what you think is best,” her husband Elkanah replied, “and stay here until you have weaned him. Only may the LORD confirm His word.” So Hannah stayed and nursed her son until she had weaned him.

24 Once she had weaned him, Hannah took the boy with her, along with a three-year-old bull, an ephah of flour, and a skin of wine. Though the boy was still young, she brought him to the house of the LORD at Shiloh.
