(Mat. 5:25-26) “25 Agree with your adversary quickly, whiles you are in the way with him; lest at any time the adversary deliver you to the judge, and the judge deliver you to the officer, and you be cast into prison. 26 Truly I say to you, You shall by no means come out there, till you have paid the uttermost farthing.”
(Luk. 12:57-59) “57 Yes, and why even of yourselves judge you not what is right? 58 When you go with your adversary to the magistrate, as you are in the way, give diligence that you may be delivered from him; lest he hale you to the judge, and the judge deliver you to the officer, and the officer cast you into prison. 59 I tell you, you shall not depart there, till you have paid the very last mite.”
This means that you should judge even of yourselves you not what is right, that is claim to a court on yourself that you did a wrong. Otherwise God will punish you much more harshly than a court.
