'Whom' in the Bible

and I saw another messenger going up from the rising of the sun, having a seal of the living God, and he did cry with a great voice to the four messengers, to whom it was given to injure the land and the sea, saying,

And the messenger whom I saw standing upon the sea, and upon the land, did lift up his hand to the heaven,

with whom the kings of the earth did commit whoredom; and made drunk from the wine of her whoredom were those inhabiting the earth;'

and he shall go forth to lead the nations astray, that are in the four corners of the earth -- Gog and Magog -- to gather them together to war, of whom the number is as the sand of the sea;
