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.
