1 Samuel 1:19-23

19The next morning they got up early to bow in worship before the LORD, and then they returned home to Ramah.

And Elkanah had relations with his wife Hannah, and the LORD remembered her. 20So in the course of time, Hannah conceived and gave birth to a son. She named him Samuel,1 saying, “Because I have asked for him from the LORD.”

21Then Elkanah and all his house went up to make the annual sacrifice to the LORD and to fulfill his vow, 22but 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.”2

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.”3

So Hannah stayed and nursed her son until she had weaned him.
