The affection which the disciples entertained for each other during the lifetime of Jesus, was thus increased tenfold after his death. They formed a little society, very retired, and they lived exclusively within themselves. The number of them at Jerusalem was one hundred and twenty.[4.2] Their piety was active, and as yet, completely restrained by the forms of Jewish religionism. The temple was their chief place of worship.[4.3] No doubt, they labored for their living; but manual labor occupied but a small place in the Jewish economy. Every Jew had a trade, and this trade implied no lack of learning or of gentle breeding. With us in our day, our material needs are so difficult to satisfy, that a man who lives by manual labor is obliged to work twelve or fifteen hours a day; the man of leisure alone can apply himself to intellectual pursuits; the acquisition of learning is a rare and expensive matter. But in these old societies, of which the East of our own day furnishes some idea; in those climates where nature is so lavish for man's wants, and exacts so little in return--the life of a laborer left plenty of leisure. A sort of method of common instruction rendered every man well up in the prevailing ideas. Food and raiment sufficed;[4.4] a few hours of moderate labor were enough to provide them. The remaining portion of the time was devoted to day-dreaming and to the indulgence of passionate love. The latter had, in the minds of these people, attained to a degree altogether inconceivable by us. The Jews of that period[4.5] appear to us as if possessed, each one obeying like a blind machine the idea which had taken possession of him.
