1 Samuel 1:22, 24-28

But Hannah did not go. She told her husband, “Wait until the boy is weaned. Then I will take him to the Tabernacle and leave him there with the LORD permanently.”

When the child was weaned, Hannah took him to the Tabernacle in Shiloh. They brought along a three-year-old bull for the sacrifice and a basket of flour and some wine. After sacrificing the bull, they brought the boy to Eli. “Sir, do you remember me?” Hannah asked. “I am the very woman who stood here several years ago praying to the LORD. I asked the LORD to give me this boy, and he has granted my request. Now I am giving him to the LORD, and he will belong to the LORD his whole life.” And they worshiped the LORD there.
