And it came to pass that he returned to his own house at Jerusalem; and he cast himself upon his bed, being overcome with the Spirit and the things which he had seen.
And being thus overcome with the Spirit, he was carried away in a vision, even that he saw the heavens open, and he thought he saw God sitting upon his throne, surrounded with numberless concourses of angels in the attitude of singing and praising their God.
And it came to pass that he saw One descending out of the midst of heaven, and he beheld that his luster was above that of the sun at noon-day.
And he also saw twelve others following him, and their brightness did exceed that of the stars in the firmament.
And they came down and went forth upon the face of the earth; and the first came and stood before my father, and gave unto him a book, and bade him that he should read.
And it came to pass that as he read, he was filled with the Spirit of the Lord.
And he read, saying: Wo, wo, unto Jerusalem, for I have seen thine abominations! Yea, and many things did my father read concerning Jerusalem—that it should be destroyed, and the inhabitants thereof; many should perish by the sword, and many should be carried away captive into Babylon.
And it came to pass that when my father had read and seen many great and marvelous things, he did exclaim many things unto the Lord; such as: Great and marvelous are thy works, O Lord God Almighty! Thy throne is high in the heavens, and thy power, and goodness, and mercy are over all the inhabitants of the earth; and, because thou art merciful, thou wilt not suffer those who come unto thee that they shall perish!
And after this manner was the language of my father in the praising of his God; for his soul did rejoice, and his whole heart was filled, because of the things which he had seen, yea, which the Lord had shown unto him.
