On the eve of Passover, because of the children, so that they might not fall asleep. On the eve of the Day of Atonement,in order that they should give food to their children. Our Rabbis taught: A man is in duty bound to make his children and his household rejoice on a Festival, for it is said, And thou shalt rejoice it, thy feast, [thou and thy son, and thy daughter, etc.]<span class="x" onmousemove="('comment',' Deut. XVI, 14. Presumably the proof lies in the bracketed passage, which is absent in the text. Possibly too he reads: we-Simmakta (pi'el) 'and thou shalt cause to rejoice' instead of we-Samakta 'and thou shalt rejoice. Tosaf.'s reading, however, and Maharsha emends text accordingly, is: and thou shalt rejoice, thou and thy household (ib. XIV 26) . This refers to the eating of the second tithe in Jerusalem, and its teaching is applied here to Festivals.');"><sup>5</sup></span>
