Musar su Ecclesiaste 3:15

And the man of heart must reflect always upon what Chazal have said in Midrash Rabbah Parshath Emor 27 on the verse (Koheleth 3:15): "And G-d seeks [i.e., stands up for] the pursued." R. Huna said in the name of R. Yosef: "G-d always 'seeks' the pursued." You find a tzaddik pursuing a tzaddik — "And G-d seeks the pursued"; a tzaddik pursuing an evildoer — "And G-d seeks the pursued." R. Yehudah said in the name of R. Yossi b. Nahora: "The Holy One Blessed be He always claims the blood of the pursued from the pursuers." R. Elazar said in the name of R. Yossi b. Zimra: "It is also so with sacrifices. The Holy One Blessed be He said: 'An ox flees a lion; a goat flees a leopard; a lamb flees a wolf — Do not sacrifice before Me [animals] from the pursuers, but from the fleers.'" And if so, one must give thought to distancing himself from abetting machloketh, from taking one side over another, since, in the final analysis the Holy One Blessed be He claims their blood from his hand. And instead of emerging "the victor" and gaining honor thereby, in the end he will be seen in his shame, being punished by either tzara'ath or poverty. But if one guards himself from machloketh, he is honored by men, as it is written (Mishlei 20:3): "A man's honor is abstention from a quarrel." And Chazal have said: "Now if a man is honored by suppressing a quarrel which is his own, how much more so [is he to be censured] for intervening [and taking sides] in a quarrel which is not his own. And thus is it written (Mishlei 26:17): 'As one who seizes a dog's ears is he who grows wrathful over a quarrel that is not his.'"
