Midrash su Michea 7:19

It is said above that the school of Hillel said: "He who abounds in kindness inclines [the scale of justice] towards the side of kindness." How does He do it? R. Eliezer said: "He presses on [the side containing the virtues], as it is said (Micah 7, 19) He will turn again. He will have compassion upon us, He will suppress our iniquities." R. Jose b. Chanina says: "He lifts up the scale of sins, as it is said (Ib. 18) He lifts up iniquity and forgiveth transgression." It was taught in the school of R. Ishmael that He pardons one sin after the other before they are put on the scales; and this is the divine custom." "Nevertheless," remarked Raba, "the sin itself is not blotted out, so that if one be found with more sins, this one is added to the rest." He who overlooks retaliation [does not insist on retaliation], all his transgressions will be pardoned; as it is said (Micah 7, 18) He pardoneth iniquity and forgiveth transgression. From whom does He remove iniquity? From him who forgiveth transgression [committed against him by his neighbor]. "R. Huna, the son of R. Joshua, fell sick, and R. Papa went to visit him. Observing that the patient was in a critical condition, he said to those present: "Make ready his provisions (shrouds)." Finally he recovered, and R. Papa was ashamed to see him. "Why did you consider him so sick?" said the family. "He was so, indeed," replied R. Papa, "but the Holy One, praised be He! said, that since he never insisted on retaliation, he shall therefore be forgiven," as it is said: "He pardoneth iniquity and forgiveth transgression." From whom does He remove in-friend's transgression." R. Acha b. Canina said: "The end of the passage is like a fat tail [that of an Arabian sheep] with a thorn [stuck] through it [that will stick those who lay hold of it.]" The remnant of His inheritance, and not all His inheritance; i.e., only those who conduct themselves (modestly) like a remnant.
