1 Samuel 1:22-24

22But Hannah did not go up, for she said to her husband, “Not until the child is weaned; then I will take him, that he may appear before the Lord and remain there forever.”

23So Elkanah her husband said to her, “Do what seems best to you; wait until you have weaned him. Only let the Lord establish His word.” Then the woman stayed and nursed her son until she had weaned him.

24Now 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.
