Though Paul sat, a diligent student, at the feet of Gamaliel, he also learned a trade. He was an educated tentmaker. It was the custom among the Jews, the wealthy as well as the poorer classes, to train their sons and daughters to some useful employment, so that should adverse circumstances come, they would not be dependent on others, but would have educated ability to provide for their own necessities. They might be instructed in literary lines, but they must also be trained to some craft. This was deemed an indispensable part of their education. (TDG 203.2) MC VC
