'Hosts' in the Bible

David steadily grew more powerful, and the Lord of Hosts was with him.

“Now this is what you will say to My servant David: ‘This is what the Lord of Hosts says: I took you from the pasture and from following the sheep to be ruler over My people Israel.

Let Your name be confirmed and magnified forever in the saying, “Yahweh of Hosts, the God of Israel, is God over Israel.” May the house of Your servant David be established before You.
