Midrash su Michea 7:4

(Fol. 11) Our Rabbis were taught: "When the community of Israel is in trouble and one withdraws himself from them [refusing to share their sorrow], two ministering angels who accompany each man lay their hands upon his head and say: 'The Baraitha we are taught: "When the community when in distress shall not live to see the relief of the community.' " In another Baraitha we are taught that when the community is in distress one must not say: 'I will go to my house, eat, drink and make myself comfortable'; for concerning him the passage reads (Is. 22, 13) And behold {there are) joy and gladness, in staying oxen, and killing sheep, eating flesh, and drinking wine; 'Let us eat and drink; for tomorrow) we must die'; and immediately follows: Truly this iniquity shall not be purged from you till you die. But a man must suffer (deny himself enjoyment), when the community suffers: for thus we find that Moses afflicted himself when the community suffered; as it is said (Ex. 17, 12) But when the hands of Moses became heavy, they took a stone, and put it under him, and he sat thereon. Did not Moses possess a pillow or bolster upon which he could have sat down? Yea; but Moses said thus: 'Since Israel lives in trouble I must therefore share their woes.' And he who afflicts himself in sympathy with the community, will live to see the relief of the community. One might perhaps say: 'Who will testify that I did not share the suffering of the community?' He should know that the stones and beams of his very house will bear testimony to this fact; as it is said (Hab. 2, 11) For the stone will cry out of the wall, and the beam out of the woodwork will answer it." In the college of R. Shila it was said that the two angels who accompany a man will testify against him; as it is said (Ps. 91, 11) For his angels will he given charge concerning thee. R. Chidka says: "The soul of man will testify against him; as it is said (Micah 7, 4) Keep the doors of thy mouth from her that lieth in thy bosom." Still others say that the members of a man's body will testify against him; as it is said (Is. 43, 10) Ye are my witnesses, saith the Lord.
