After having performed this service to his brethren, he retired to the pulpit, the vails being dropped, and bowed himself with O. Cowdery, in solemn, but silent prayer to the Most High. After rising from prayer the following vision was opened to both of them.

. . . .the Heavens were again opened unto them and Moses appeared before them and committed unto them the Keys of the gathering of Israel from the four parts of the Eearth and the leading of the ten tribes from the Land of the North. After this Elias appeared and committed the dispensation of the gospel of Abraham, saying, that in them and their seed all generations after them should be blessed. After this vision had closed, another great and glorious vision burts upon them, for Elijah, the Prophet, who was taken to Heaven without tasting death, also stood before them, and said, behold the time has fully come which was spoken of by the mouth of Malachi, testifying, that he should be sent before the great and dreadful day of the Lord come, to turn the hearts of the Fathers to the children, and the children to the fathers, lest the whole earth be smitten with a curse. Therefore, the Keys of this dispensation are committed into your hands, and by this ye may know that the great and the dreadful day of the Lord is near, even at the doors
