Midrasch zu Dewarim 16:20

Rabban Johanan ben Zakkay said: (Mal. 3:5:) THEN I WILL DRAW NEAR TO YOU IN JUDGMENT; [AND I WILL BE A SWIFT WITNESS AGAINST SORCERERS, AGAINST ADULTERERS, AGAINST THOSE WHO SWEAR TO A LIE, AGAINST THOSE WHO OPPRESS THE HIRED WORKER IN THEIR WAGES, THE WIDOW, THE ORPHAN AND THOSE WHO TURN ASIDE THE SOJOURNER]. Woe to us for the day of judgment! Woe to us for the day of retribution!³³Cf. Gen. R. 93:6; Numb. R. 10:2. Scripture compares (heqish) one who turns aside justice to all the worst transgressions. Therefore the Holy One warned (in Deut. 16:19): YOU SHALL NOT TURN ASIDE <JUSTICE>. R. Hama bar Osha'ya said: A person having a pain in his eye gives a lot of money to a physician, <when> it is doubtful whether he is being healed or not.³⁴Ket. 105a. But the one who takes a bribe corrupts justice, makes her eyes blind, causes exile for Israel, and brings hunger into the world. Thus it is stated (in Deut. 16:20): JUSTICE, JUSTICE YOU SHALL PURSUE SO THAT YOU MAY LIVE AND POSSESS <THE LAND>; and if not, you shall not possess it.

(Deut. 16:20): JUSTICE, JUSTICE YOU SHALL PURSUE, [<with JUSTICE repeated> two times]. From here they have maintained that one should pursue a worthy court.

Another interpretation of (Deut. 16:20): JUSTICE, JUSTICE YOU SHALL PURSUE, <with JUSTICE repeated> two times. <Here is> a warning for judges who judge capital cases not to render judgment on the same day as the trial. Rather let them suspend the judgment overnight (rt.: LWN), just as they suspend it overnight (rt.: LWN) in Jerusalem, since it is stated (in Is. 1:21): [SHE (i.e., Jerusalem) WAS FULL OF JUSTICE,] FOR RIGHTEOUSNESS LODGED (rt.: LWN) THERE.
