'Lord of Hosts' in the Bible

And she vowed a vow and said, O, Lord of Hosts, if You will indeed look upon the affliction of Your handmaid and remember me, and not forget Your handmaid, but will give to Your handmaid a man-child, then I will give him to Jehovah all the days of his life, and there shall no razor come upon his head.

So says the Lord of Hosts, the God of Israel, to all the exiles whom I caused to be exiled from Jerusalem to Babylon:

And as Isaiah said before, "Unless the Lord of hosts had left us a seed, we would have been as Sodom, and would have been like Gomorrah."

Behold, the hire of the laborers reaping your fields cry out, being kept back by you. And the cries of those who have reaped have entered into the ears of the Lord of hosts.
