1 Samuel 1:27

24and she causes him to go up with her when she has weaned him, with three bullocks, and one ephah of flour, and a bottle of wine, and she brings him into the house of YHWH at Shiloh, and the youth [is but] a youth.

25And they slaughter the bullock, and bring in the youth to Eli,

26and she says, “O my lord, your soul lives! My lord, I [am] the woman who stood with you in this [place], to pray to YHWH;

27I prayed for this youth, and YHWH gives to me my petition which I asked of Him;

28and I also have called him to YHWH, all the days that he has lived—he is called to YHWH”; and he bows himself there before YHWH.
