(Exodus 21:31) "If the ox gore a man-servant or a maid-servant." These, too, were in the class of "and it kill a man or a woman," and Scripture singled them out for both lenity and severity. For lenity — If he were worth a hundred maneh, he pays thirty selaim. For severity — If he were worth only a dinar, he pays thirty selaim.
