Num. V, 13. The English Version translates the verb she be not taken in the act; but the Rabbis understood it in the sense that she was not forced to misconduct and was a consenting party. Cf. the use of the same verb in Deut. XXII, 28. If she had been violated, she was exempt from the ordeal. ');"><sup>3</sup></span>
