'Hosts' in the Bible

She {made a vow} and said: "O Yahweh of hosts, if you will look with compassion on the misery of your female servant, and will remember me, and not forget your female servant, and will give to your female servant {a male child} then I will give him to Yahweh all the days of his life, and a razor will never pass over his head."

So the army sent to Shiloh and brought from there the ark of the covenant of Yahweh of hosts who sits [between] the cherubim. And the two sons of Eli, Hophni and Phinehas, [were] there with the ark of the covenant of God.

But they forgot Yahweh their God, so he sold them into the hand of Sisera, commander of the hosts of Hazor, and into the hand of [the] Philistines, and into the hand of the king of Moab, and they fought against them.

Thus says Yahweh of hosts: 'I have observed what Amalek did to Israel, {how he opposed him} when he went up from Egypt.

Then David said to the Philistine, "You [are] coming to me with a sword and with a spear and with a javelin, but I am coming to you in the name of Yahweh of hosts, the God of the battle lines of Israel, whom you have defied!
