Matthew 7:2
1 “Do not judge so that you will not be judged. 2 For by the standard you judge you will be judged, and the measure you use will be the measure you receive. 3 Why do you see the speck in your brother’s eye, but fail to see the beam of wood in your own? 4 Or how can you say to your brother, ‘Let me remove the speck from your eye,’ while there is a beam in your own?
Megillah 28a
Babylonian TalmudHe also said: Nor was I ever inflexible in exacting a measure of retribution against those who wronged me. This is referring to conduct such as that which Rava said: Anyone who overlooks exacting a measure of retribution against those who wronged him, all his transgressions are removed from him, as it is stated: “He pardons iniquity and overlooks transgression” (Micah 7:18), which is homiletically read as saying: For whom does He pardon iniquity? For he who overlooks transgressions that others have committed against him.

"... Because of his consistent pursuit of humility and peace, numerous scholars on this period have seen Hillel as the antitype to the egocentric, despotic, violent, oppressive, worldly ruler, Herod the Great. In practical application, these foundational principles required that Hillel emphasize leniency in judgment (Mishnah Avot 2:5). He taught a view of divine judgment that within the Academy came to be called “measure for measure” (Mishnah Avot 2:7; Babylonian Talmud; compare Matthew 7:2). In his understanding, if a man exhibited prejudice or was unnecessarily harsh in passing judgment, God would dispense the same measure of judgment back to him. Instead, he taught, “Judge not your fellow man until you have come into his place” and “Judge your fellow man toward the side of the scale of merit [i.e., when in doubt, give the benefit of the doubt to the accused]” (Mishnah Avot 2:5; Derekh Eretz Zuta 3; compare Matthew 7:1; Romans 14:10). Our modern “presumption of innocence” legal principle is an outgrowth of this approach to jurisprudence ..."
