'Whom' in the Bible

Don't you be like your fathers, to whom the former prophets proclaimed, saying: Thus says Yahweh of Armies, 'Return now from your evil ways, and from your evil doings;' but they did not hear, nor listen to me, says Yahweh.

I will pour on the house of David, and on the inhabitants of Jerusalem, the spirit of grace and of supplication; and they will look to me whom they have pierced; and they shall mourn for him, as one mourns for his only son, and will grieve bitterly for him, as one grieves for his firstborn.
