DEUT16 [This verse]. We have been admonished herein to believe that no harm will befall us when we adjudicate justly, without any bias, as our Sages, z"l, said (Pesachim 8a), "The emissaries sent to perform a mitzvah face no harm, neither on their way nor on their return." This is what is meant by "for it is God's judgment" [I.e., and the judge is God's emissary to perform the mitzvah of adjudicating His judgment (Zeh Hasha'ar)] -- no harm will befall you from it.
