Kabbalah к Берешит 14:18

There are true candles in these precious garments, garments of truth, perfection of truth and luminaries of truth. They are the perfections of the King’s throne, who is Binah, called righteousness and justice. They are Zeir Anpin called justice and Malchut called righteousness. They are the beginning and completion of the entire faith; righteousness is in the beginning, while the manifestation of its completion is called justice. All judgments on high and low are crowned with these, and everything is hidden within justice, which is Zeir Anpin. And righteousness (Tzedek), which is Malchut, is sustained by this justice, which is Zeir Anpin. Malchut is sometimes called, “Melchizedek, king of Shalem” (Bereshit 14:18).
