'Lord of Hosts' in the Bible

And David arose, and went with all the people that were with him from Baale of Judah, to bring up from there the ark of God, whose name is called by the name of the LORD of hosts who dwells between the cherubim.

And as soon as David had made an end of offering burnt offerings and peace offerings, he blessed the people in the name of the LORD of hosts.

Now therefore so shall you say unto my servant David, Thus says the LORD of hosts, I took you from the sheepfold, from following the sheep, to be ruler over my people, over Israel:

And let your name be magnified forever, saying, {} The LORD of hosts is the God over Israel: and let the house of your servant David be established before you.

For you, O LORD of hosts, God of Israel, have revealed to your servant, saying, I will build you a house: therefore has your servant found in his heart to pray this prayer unto you.
