"But when this Antichrist shall have devastated all things in this world, he will reign for three years and six months, and
sit in the temple at Jerusalem; and then the Lord will come from heaven in the clouds, in the glory of the Father, sending this man and those who follow him into the lake of fire; but bringing in for the righteous the times of the kingdom, that is, the rest, the hallowed seventh day; and restoring to Abraham the promised inheritance, in which kingdom the Lord declared, that “many coming from the east and from the west should sit down with Abraham, Isaac, and Jacob.”4709"
