1 Samuel 1:20-22

20 And so it was, when the days had come round during which Hannah was with child, that she bare a son, and called his name Samuel, Because, of Yahweh, I asked him.

21 And the man Elkanah, and all his house, went up, to offer unto Yahweh the yearly sacrifice, and each his own vow.

22 But, Hannah, went not up, for she said to her husband Not till the boy is weaned, then will I take him, and he shall appear before Yahweh, and abide there evermore.
