Joshua warmly expressed his disapproval of the numerous measures which the school of Shammai had introduced before the destruction of the Temple, under the name of "the eighteen rules," and which rendered impossible all closer relations or friendly communications with the heathens. He said, "On that day, the school of Shammai went beyond all bounds in their decisions; they behaved as one who pours water into a vessel containing oil; the more water one pours in, the more oil runs off," which meant that, by introducing a number of superfluous details, the really important things were lost. Joshua seems also to have opposed the unmeasured deductions of the Hillelite school. He said that the regulations respecting the Sabbath, festive offerings, and misuse of holy things, have but slight foundation in Holy Writ, but have many Halachas in their support. The balanced and calm character of Joshua rendered him especially fitted for the part of intermediary between the Jewish nation and Roman intolerance. He was the only teacher who sought and enjoyed the confidence of the Roman rulers; without betraying his trust to the Romans, he yet persuaded the opposing forces to be mutually more yielding. The death of Gamaliel, and the hostile attitude of the Jews towards the Romans during the last years of the Emperor Trajan and the early years of Hadrian's reign, seem to have torn Joshua away from his petty trade, and to have put the public leadership into his hands. It is not improbable that he assumed the patriarchal position; at least the circumstance that he removed the ban from Eliezer after the latter's death, an act which could be performed only by a patriarch, or one equal in authority, affords some ground for this supposition. Joshua's activity during the last years of his life forms an important part of the history of his times.
