Charles H. Spurgeon on Psalms 26:1

Whole Psalm. This Psalm is coupled on to the foregoing by thoughts and words. At the close of the foregoing the psalmist had prayed for integrity Ps 26:1. Unless this Psalm is regarded as a sequel to the preceding one, it will seem vainglorious; but being combined with the penitential acknowledgments of sin, and with the earnest supplications for pardon and grace, and with the earnest profession of faith that God has heard his prayer, which breathe forth in the foregoing Psalm, it will be seen that the declarations which the psalmist now makes of integrity, are not assertions of human merit, but acknowledgments of divine mercy. As Augustine says, "Non merita mea, sed misericordia tua, ante oculos meos est." Christopher Wordsworth.

Judge me, O Lord; for I have walked in mine integrity. A good cause, a good conscience, and a good deportment, are good grounds of appeal to God. Ingram Cobbin.
