1 Samuel 1:19-23

Then they got up early in the morning and worshiped before the Lord, and returned again to their house in Ramah. And Elkanah had relations with Hannah his wife, and the Lord remembered her.

It came about in due time, after Hannah had conceived, that she gave birth to a son; and she named him Samuel, saying, “Because I have asked for him of the Lord.”

Then the man Elkanah went up with all his household to offer to the Lord the yearly sacrifice and to pay his vow.

But Hannah did not go up, for she said to her husband, “I will not go until the child is weaned; then I will bring him, so that he may appear before the Lord and stay there for life.”

Elkanah her husband said to her, “Do what seems best to you. Stay until you have weaned him; only may the Lord confirm His word.” So the woman stayed and nursed her son until she weaned him.
