Rashi on Exodus 23:8/רש"י על שמות כ״ג:ח׳

1ושחד לא תקח AND THOU SHALT TAKE NO GIFT, even if you mean to give a true judgment in favour of the giver, and it is a matter of course that you must not accept one to wrest judgment, and therefore there is no need for Scripture to forbid this, for with regard to wresting judgment, whether you take a bribe or not, it is distinctly stated, (Deuteronomy 16:19) “Thou shalt not wrest judgment” (Ketubot 105a).

2יעור פקחים [FOR THE BRIBE] BLINDETH THE OPEN-EYED — Even if he be well-versed in the Torah and takes a bribe, in the end his mind will become confused, what he has learnt will be forgotten, and the light of his eyes will become dim (Mekhilta; Ketubot 105a).

3ויסלף — render it as the Targum does: ויקלקל “makes bad”, “perverts”. ...

4דברי צדיקים means, the words which have been described by the term “righteous”, viz., the judgments of truth uttered on Sinai. Thus, too, does the Targum take it: words that are תריצין, upright.
