1 Samuel 1:11, 22, 27-28

And she made this vow: “O LORD of Heaven’s Armies, if you will look upon my sorrow and answer my prayer and give me a son, then I will give him back to you. He will be yours for his entire lifetime, and as a sign that he has been dedicated to the LORD, his hair will never be cut.”

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.”

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.
