'Armies' in the Bible

David grew greater and greater; for Yahweh of Armies was with him.

Also the mighty men of the armies: Asahel the brother of Joab, Elhanan the son of Dodo of Bethlehem,

"Now therefore, you shall tell my servant David, 'Thus says Yahweh of Armies, "I took you from the sheep pen, from following the sheep, that you should be prince over my people Israel.

Let your name be established and magnified forever, saying, 'Yahweh of Armies is the God of Israel, even a God to Israel. The house of David your servant is established before you.'
