Her rival provoked her sore, to make her fret, because Yahweh had shut up her womb.
The name "Lord of hosts" occurs first in the Old Testament in 1 Samuel 1:3. [Note: See Matitiahu Tsevat, "Studies in the Book of Samuel," Hebrew Union College Annual 36 (1965):49-58.] This is a very commonly used divine titulary (a title that became a name) in the rest of Samuel, Kings, Chronicles, and the prophetic books. The "hosts" are the armies of the sovereign God and consist of humans (1 Samuel 17:45), angels (Joshua 5:14), and stars (Isaiah 40:26). This name expresses the infinite resources and power at God’s disposal as He fights for His people.
