הדר זכה בהו הדר יהיב ליה פלגא דזוזא ואפקרה חזייה דהוה קא בעי למיהדר למזכיה בהו א"ל לכולי עלמא אפקרנהו ולך לא אפקרנהו
For a Master said: A man's affinity takes away a sixtieth of his illness: yet even so, he must visit him 'Therein to burial.' But that [too] is identical with the practice of loving deeds? — That is necessary only in respect of an old man for whom it is undignified.<span class="x" onmousemove="('comment',' Yet even he must take part in burial. ');"><sup>16</sup></span> 'That they shall do — this means [acts] beyond the requirements of the law.' For R. Johanan said: Jerusalem was destroyed only because they gave judgments therein in accordance with Biblical law. Were they then to have judged in accordance with untrained arbitrators?<span class="x" onmousemove="('comment',' [ [H] from [H], 'to cut,' 'to decide;' so Jast. Cf. however B.K. (Sonc. ed.) p. 671, n. 10.] ');"><sup>17</sup></span> — But say thus: because they based their judgments [strictly] upon Biblical law, and did not go beyond the requirements of the law.
