'Lord of Hosts' in the Bible

And David arose and went with all the people who were with him to Baale-judah, to bring up from there the ark of God which is called by the Name, the very name of the Lord of hosts who is enthroned above the cherubim.

When David had finished offering the burnt offering and the peace offering, he blessed the people in the name of the Lord of hosts.

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

that Your name may be magnified forever, by saying, ‘The Lord of hosts is God over Israel’; and may the house of Your servant David be established before You.

For You, O Lord of hosts, the God of Israel, have made a revelation to Your servant, saying, ‘I will build you a house’; therefore Your servant has found courage to pray this prayer to You.
