'Lord of Hosts' in the Bible

Behold, I am against you, says the LORD of hosts, and I will burn her chariots in the smoke, and the sword shall devour your young lions: and I will cut off your prey from the earth, and the voice of your messengers shall no more be heard.

Behold, I am against you, says the LORD of hosts; and I will uncover your skirts over your face, and I will show the nations your nakedness, and the kingdoms your shame.
