Here we have David in sorrow. 1. It is a great sorrow, to such a degree that he weeps rivers of tears. Commonly, where there is a gracious heart, there is a weeping eye, in conformity to Christ, who was a man of sorrows and acquainted with grief. David had prayed for comfort in God's favour (Psa 119:135), now he pleads that he was qualified for that comfort, and had need of it, for he was one of those that mourned in Zion, and those that do so shall be comforted, Isa 61:3. 2. It is godly sorrow. He wept not for his troubles, though they were many, but for the dishonour done to God: Because they keep not thy law, either because my eyes keep not thy law, so some (the eye is the inlet and outlet of a great deal of sin, and therefore it ought to be a weeping eye), or, rather, they, that is, those about me, Psa 119:139. Note, The sins of sinners are the sorrows of saints. We must mourn for that which we cannot mend.
