'Do You Not Know' in the Bible

Have you not asked them that go by the way? and do you not know their evidences,

God has not cast away his people whom he foreknew. Do you not know what the scripture says of Elijah? how he makes intercession to God against Israel, saying,

Do you not know that the saints shall judge the world? and if the world shall be judged by you, are you unworthy to judge the smallest matters?

Do you not know that they who minister about holy things live of the things of the temple? and they who wait at the altar are partakers with the altar?
