المزامير ١١٩:١٣٧

The eightfold Tsade. God rules righteously and faithfully according to His word, for which the poet is accordingly zealous, although young and despised. The predicate ישׂר in Psa 119:137 precedes its subject משׁפּטיך (God's decisions in word and in deed) in the primary form (after the model of the verbal clause Psa 124:5), just as in German [and English] the predicative adjective remains undeclined. The accusatives צדק and אמוּנה in Psa 119:138 are not predicative (Hitzig), to which the former ("as righteousness") - not the latter however - is not suited, but adverbial accusatives (in righteousness, in faithfulness), and מאד according to its position is subordinate to ואמונה as a virtual adjective (cf. Isa 47:9): the requirements of the revealed law proceed from a disposition towards and mode of dealing with men which is strictly determined by His holiness (צדק), and beyond measure faithfully and honestly designs the well-being of men (אמונה מאד). To see this good law of God despised by his persecutors stirs the poet up with a zeal, which brings him, from their side, to the brink of extreme destruction (Psa 69:10, cf. צמתּת, Psa 88:17). God's own utterance is indeed without spot, and therefore not to be carped at; it is pure, fire-proved, noblest metal (Psa 18:31; Psa 12:7), therefore he loves it, and does not, though young (lxx νεώτερος, Vulgate adolescentulus) and lightly esteemed, care for the remonstrances of his proud opponents who are old and more learned than himself (the organization of Psa 119:141 is like Psa 119:95, and frequently). The righteousness (צדקה) of the God of revelation becomes eternal righteousness (צדק), and His law remains eternal truth (אמת). צדקה is here the name of the attribute and of the action that is conditioned in accordance with it; צד…

Here is, 1. The righteousness of God, the infinite rectitude and perfection of his nature. As he is what he is, so he is what he should be, and in every thing acts as becomes him; there is nothing wanting, nothing amiss, in God; his will is the eternal rule of equity, and he is righteous, for he does all according to it. 2. The righteousness of his government. He rules the world by his providence, according to the principles of justice, and never did, nor ever can do, any wrong to any of his creatures: Upright are thy judgments, the promises and threatenings and the executions of both. Every word of God is pure, and he will be true to it; he perfectly knows the merits of every cause and will judge accordingly. 3. The righteousness of his commands, which he has given to be the rule of our obedience: "Thy testimonies that thou hast commanded, which are backed with thy sovereign authority, and to which thou dost require our obedience, are exceedingly righteous and faithful, righteousness and faithfulness itself." As he acts like himself, so his law requires that we act like ourselves and like him, that we be just to ourselves and to all we deal with, true to all the engagements we lay ourselves under both to God and man. That which we are commanded to practise is righteous; that which we are commanded to believe is faithful. It is necessary to our faith and obedience that we be convinced of this.

119:137-144 Tsadhe (צ): God is righteous, and his word is right and just, especially in contrast to the deceptions of the wicked.
