1 Samuel 1:22, 24-28

But one time Hannah did not go with him. She told him, “When the boy is old enough to eat solid food, I will take him to Shiloh. Then I will give him to the LORD, and he will always live there.”

When Samuel was old enough to eat, Hannah took him to the house of the LORD at Shiloh, along with a three-year-old bull, one-half bushel of flour, and a leather bag filled with wine. After they had killed the bull for the sacrifice, Hannah brought Samuel to Eli. She said to Eli, “As surely as you live, sir, I am the same woman who stood near you praying to the LORD. I prayed for this child, and the LORD answered my prayer and gave him to me. Now I give him back to the LORD. He will belong to the LORD all his life.” And he worshiped the LORD there.
