"Among the Jews professional life was limited. The one widely extensive profession was that of rabbi,
if profession it might be called, for most rabbis followed some trade or secular pursuit for a livelihood, while devoting
all the time possible to the study and teaching of the law. . . . Every Jewish boy was expected to learn some trade. Rabbinic
tradition declared that "whoever does not teach his son a trade is as if he brought him up to be a robber'" (p. 149)
use of tents [by travelers] made the tent-making trade a lucrative occupation. One belonging to the same trade-guild, religious
cult, or having any other personal relationship to any resident of the locality could nearly always find welcome more or less
genuine in a private home. . . . This was the prevailing manner in which the first Christian missionaries were provided
for, though likely the entertainment was tendered them without cost (cf. 2 John 10-11; 3 John 5-8)" (p. 221).
