'Lord of Hosts' in the Bible

And as Esaias said before, "Except the Lord of hosts had left us a seed, we had been as Sodom, and we had been made like unto Gomorrah."

Behold the hire of the laborers, that reaped your fields, of which they are defrauded by you, crieth out against you: and the complaints of the reapers are come into the ears of the Lord of hosts.
