'Lord God of Hosts' in the Bible

Hate the evil, and love the good, and establish justice in the gate: it may be that the LORD God of hosts will be gracious unto the remnant of Joseph.

And the Lord GOD of hosts is he that touches the land, and it shall melt, and all that dwell in it shall mourn: and it shall rise up wholly like the river; and shall be drowned, as by the river of Egypt.
