On the mountain called "Shelem, because of its exceeding height" (did it reach to Heaven?), the brother of Jared prays to the Lord. His prayer starts with good basic temple doctrine: God is in the heavens, and man is fallen. Nevertheless, man is urged to "call upon the Lord" to receive according to his desires (compare Matthew -- this is the language of the triple petition).
The Lord comes out through the veil. He explicitly tells the brother of Jared that his coming forward through the veil is a prophecy of his taking on flesh and blood. We have already seen that John and Alma both saw it the same way.
