Mishnah for Nedarim 78:18

רב חלבו חלש נפק אכריז רב כהנא

This teaches that the sun and the moon ascended from the raki'a to the zebul and exclaimed before Him, 'Sovereign of the Universe! If thou wilt execute judgment for Amram's son,<span class="x" onmousemove="('comment',' By punishing Korah and his confederates. ');">¹⁷</span> we will give forth our light; if not, we will not shine.' In that moment He shot spears and arrows at them. 'Every day,' He rebuked them, 'men worship you, and yet you give your light. For My honour you do not protest, yet you protest for the honour of flesh and blood.' [Since then,] spears and arrows are shot at them every day before they consent to shine,<span class="x" onmousemove="('comment',' Accepting the Almighty's rebuke, they refuse to shine, because of the insult to His glory, until they are forced to. ');">¹⁸</span> as it is written, And at the light of thy arrows they go, etc.<span class="x" onmousemove="('comment',' Ibid. ');">¹⁹</span> It was taught: There is no measure for visiting the sick. What is meant by, 'there is no measure for visiting the sick?' R. Joseph thought to explain it: its reward is unlimited. Said Abaye to him: Is there a definite measure of reward for any precept? But we learnt: Be as heedful of a light precept as of a serious one, for thou knowest not the grant of reward for precepts? But Abaye explained it: Even a great person must visit a humble one. Raba said: [One must visit] even a hundred times a day. R. Abba son of R. Hanina said: He who visits an invalid takes away a sixtieth of his pain.<span class="x" onmousemove="('comment',' A variant: his sickness. ');">²⁰</span> Said they to him: If so, let sixty people visit him and restore him to health? — He replied: The sixtieth is as the tenth spoken of in the school of Rabbi, and [providing further that] he [the visitor] is of his affinity.<span class="x" onmousemove="('comment',' As the invalid. Born under the same planetary influence, Asheri; Rashi (and last.) 'of the same age'. ');">²¹</span> For it was taught: Rabbi said: A daughter who enjoys maintenance from her brothers' estate receives a tenth of the estate.<span class="x" onmousemove="('comment',' She can, on marriage, demand a tenth of the estate for a dowry and trousseau. V. Keth. 68a. ');">²²</span> Said they to Rabbi: If so, if a man leaves ten daughters and one son, the latter receives nothing! He replied: The first [to marry] receives a tenth of the estate; the second, a tenth of the residue; the third, a tenth of what remains. [Now, if they all married at the same time], they redivide equally.<span class="x" onmousemove="('comment',' I.e., after taking one tenth of the estate, and another a tenth of what is left, and a third likewise, etc., they pool the lot together, and divide it equally. — Thus here too, the first visitor with the same affinity takes away a sixtieth of the sickness; the second a sixtieth of the remainder, and so on. Hence he would not be completely cured. ');">²³</span> R. Helbo fell ill. Thereupon R. Kahana went and proclaimed:
