Psalms 119:137

TZADDI. Righteous you are, O Lord
Essentially, originally, and of himself; naturally, immutably, and universally, in all his ways and works of nature and grace; in his thoughts, purposes, counsels, and decrees; in all the dispensations of his providence; in redemption, in the justification of a sinner, in the pardon of sin, and in the gift of eternal life through Christ;

and upright [are] your judgments ;
they are according to the rules of justice and equity; the precepts of the word, the doctrines of the Gospel, as well as the judgments of God inflicted on wicked men, and all the providential dealings of God with his people, and also the final judgment.
