'Hosts' in the Bible

David became greater and greater, for the Lord of hosts was with him.

Now, therefore, thus shall you say to My servant David, ‘Thus says the Lord of hosts, “I took you from the pasture, from following the sheep, to be leader over My people Israel.

Let Your name be established and magnified forever, saying, ‘The Lord of hosts is the God of Israel, even a God to Israel; and the house of David Your servant is established before You.’
