'Lord of Hosts' in the Bible

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

Behold, I am against thee, saith the LORD of hosts; and I will discover thy skirts upon thy face, and I will shew the nations thy nakedness, and the kingdoms thy shame.
