לֹא־תַטֶּ֣ה מִשְׁפָּ֔ט לֹ֥א תַכִּ֖יר פָּנִ֑ים וְלֹא־תִקַּ֣ח שֹׁ֔חַד כִּ֣י הַשֹּׁ֗חַד יְעַוֵּר֙ עֵינֵ֣י חֲכָמִ֔ים וִֽיסַלֵּ֖ף דִּבְרֵ֥י צַדִּיקִֽם׃

You shall not judge unfairly: you shall show no partiality; you shall not take bribes, for bribes blind the eyes of the discerning and upset the plea of the just. 

Compare to shemot - There the warming continues not to oppress the stranger because you were strangers. But not here. 

צֶ֥דֶק צֶ֖דֶק תִּרְדֹּ֑ף לְמַ֤עַן תִּֽחְיֶה֙ וְיָרַשְׁתָּ֣ אֶת־הָאָ֔רֶץ אֲשֶׁר־יְהֹוָ֥ה אֱלֹהֶ֖יךָ נֹתֵ֥ן לָֽךְ׃ {ס}

Justice, justice shall you pursue, that you may thrive and occupy the land that your God יהוה is giving you.

Message for Elul - Rabbi Abittan - If you will pursue justice than midat hadin sits back but if not midat hadin will take care. If there is Din Below then there is no need for Din Above. If there is no Din below then there will be Din from above. 

And furthermore if you will exhibit midat hachesed verachamim, than that attribute will shine on you and judge you. 

Stories of Chesed from Rabbi Eitan Feiner 

How are we to understand the absence of the stranger, the orphan and the widow from the description of the king’s and the judge’s realms of responsibility and from the descriptions of the Kohanim and the Levites?
