'Lord of Hosts' in the Bible

Behold, I will upon thee, sayeth the LORD of Hosts, and will set fire upon thy chariots that they shall smoke withal, and the sword shall devour thy young lions. I will make an end of thy spoiling from out of the earth, and the voice of thy messengers shall no more be heard.

Behold, I will upon thee, sayeth the LORD of Hosts, and will pull thy clothes over thy head: that I may show thy nakedness among the Heathen, and thy shame among the kingdoms.
