Once, R. Yochanan b. Zakkai went up to Maon Yehudah, where he saw a young girl picking barley from under the dung of a horse, whereupon he asked (the bystanders): Did you see that young girl? What is she? They: A Hebrew. He: Who owns this horse? They: An Arab rider. R. Yochanan to his disciples: All of my days I was aggrieved over this verse, reading it and not knowing what it meant — "If you do not know, you fairest among the women" — If you did not wish to subserve Heaven, you will subserve gentiles. If you did not wish to pay the half-shekel for a head to Heaven, you will pay fifteen shekels in the kingdom of your foes.
