Vs. 142 — Your righteousness is an everlasting righteousness, And Your law is truth.
“ ‘Men,’ as Bishop Horne observes, ‘may decree wickedness by a law, or they may change their decrees, and with them what is right to-day may be wrong to-morrow; but the law of God is righteousness, and it is truth to-day and for ever.’ ” (Alexander, W. H. (1867). The Book of Praises: Being the Book of Psalms, according to the Authorized Version, with Notes Original and Selected (p. 412). London: Jackson, Walford, and Hodder.)
Here the law of God is honoured by the additional encomium, that it is everlasting righteousness and truth; as if it had been said, that all other rules of life, with whatever attractions they may appear to be recommended, are but a shadow, which quickly vanishes away. The Psalmist, no doubt, indirectly contrasts the doctrine of the law with all the human precepts which were ever delivered, that he may bring all the faithful in subjection to it, since it is the school of perfect wisdom. There may be more of plausibility in the refined and subtile disquisitions of men; but there is in them nothing firm or solid at bottom, as there is in God’s law. (Calvin, J., & Anderson, J. (2010).

I profess with my whole heart, O’ Lord, that Your righteousness is an everlasting righteousness, and Your law is truth. Therefore I will delight in it. Enabled by the Spirit of God, I will cling to it, embracing it as with every heart beat within my chest.
