Matthew Henry's Complete Bible Commentary

Verses 137—138

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. MHBCC 598.123
