About this time, Joseph leaves Philadelphia for Washington with Orrin Porter Rockwell, Judge Higbee, and Dr. Foster, having left Sidney Rigdon sick in Philadelphia. During his stay in Philadelphia, Joseph had met with some of the Twelve on their way to England, and had held a conference wherein he "arose like a lion about to roar; and being full of the Holy Ghost, spoke in great power. . . . The entire congregation were astounded; electrified, as it were, and overwhelmed with the sense of the truth and power by which he spoke, and the wonders which he related. . . . Multitudes were baptized in Philadelphia and in the regions around."
