The apostles henceforth separated no more, except to make temporary journeys. Jerusalem became their head-quarters; they seemed to be afraid to disperse, while certain acts served to reveal in them the prepossession of being opposed to return again into Galilee, which latter had dissolved its little society. An express order of Jesus is supposed to have interdicted their quitting Jerusalem, before, at least, the great manifestations which were to take place. People's thoughts were turned with great force toward a promise which it was supposed Jesus had made. During his lifetime Jesus, it was said, had often spoken of the Holy Spirit, which was understood to mean a personification of divine wisdom. He had promised his disciples that the Spirit would nerve them in the combats that they would have to engage in, would be their inspirer in difficulties, and their advocate if they had to speak in public. Sometimes it was supposed that Jesus suddenly presented himself in the midst of his disciples assembled, and breathed on them out of his own mouth a current of vivifying air. At other times the disappearance of Jesus was regarded as a premonition of the coming of the Spirit. Many people established an intimate connection between this descent and the restoration of the kingdom of Israel. The affection that the disciples had the one for the other, while Jesus was alive, was thus enhanced tenfold after his death. They formed a very small and very retired society, and lived exclusively by themselves. At Jerusalem they numbered about one hundred and twenty. Their piety was active, and, as yet, completely restrained by the forms of Jewish piety. The Temple was then the chief place of devotion. They worked, no doubt, for a living; but at that time manual labor in Jewish society engaged very few. Everyone had a trade, but that trade by no means hindered a man from being educated and well-bred.
