therefore also I have granted him to Yahweh; as long as he lives he is granted to Yahweh. He worshiped Yahweh there.
The "he" who worshipped before the Lord (1 Samuel 1:28) may refer to Elkanah, the leader of the family and the main man in the context. It might also refer to Eli to whom Hannah was speaking. [Note: Youngblood, p. 575.] I think it probably refers to Samuel, the most immediate antecedent of "he" in 1 Samuel 1:28. If this interpretation is correct, this reference marks the beginning of Samuel’s ministry, which all of chapter 1 anticipates.
