1 Samuel 1:24-28

24Once she had weaned him, Hannah took the boy with her, along with a three-year-old bull,1 an ephah of flour,2 and a skin of wine. Though the boy was still young, she brought him to the house of the LORD at Shiloh. 25And when they had slaughtered the bull, they brought the boy to Eli.

26“Please, my lord,” said Hannah, “as surely as you live, my lord, I am the woman who stood here beside you praying to the LORD. 27I prayed for this boy, and since the LORD has granted me what I asked of Him, 28I now dedicate the boy to the LORD. For as long as he lives, he is dedicated to the LORD.”

So they worshiped3 the LORD there.
