1. Judge me, O Jehovah! I have just said, that David betakes himself to the judgment of God, because he found neither equity nor humanity among men. The Hebrew word which is rendered to judge, signifies to undertake the cognisance of a cause.

2. Prove me, O Jehovah! The more that David observed himself basely and undeservedly pursued with calumnies, the more powerfully was he excited by the vehemence of his grief fearlessly to assert his rectitude.

3. For thy goodness is before mine eyes. This verse may be viewed as one sentence, or divided into two parts, but with almost the same sense. If the former reading is adopted, both the verbs will be emphatic, after this manner: ”Because thy goodness, O Lord, has been ever before mine eyes, and I…

4. I have not sat with vain men. He again declares the very great dissimilarity which existed between him and his adversaries. For the contrast is always to be observed, that wicked men, by all the harm and mischief they wrought against him, could never drive him from the path of rectitude.

5. I hate the assembly. The Psalmist protests again how greatly he abhorred the ungodly. Formerly he denied that he had any fellowship with them; now he still more explicitly declares that he fled from their company with loathing, for that is the meaning of the phrase, I hate.

6. I will wash my hands in purity. Referring, in these words, to the ordinary use of the sacrifices, he makes a distinction between himself and those who professed to offer the same divine worship, and thrust themselves forward in the services of the sanctuary, as if they alone had the sole right…

7. That I may make men to hear, etc In these words, he shows that he referred the sacrifices to their proper use and design, which hypocrites were far from doing.

8. O Jehovah! I have loved, etc In this verse he confirms what he had said before, that he came not into the sanctuary in a careless manner, but with serious devotion.

9. Gather not my soul with wicked men. Having now affirmed his innocence, he has recourse again to prayer, and calls upon God to defend him. At first sight, indeed, it appears strange to pray that God would not involve a righteous man in the same destruction with the wicked; but God, with paternal…

10. For in their hands is maliciousness. The Hebrew word זמה, zimmah, signifies properly an inward stratagem, or device. But here it is not improperly applied to the hands, because David wished to intimate, that the wicked, of whom he was speaking, not only secretly imagined deceits, but also…

11. But I will walk in mine integrity. In this repetition there is to be remarked a circumstance which more clearly illustrates David’s righteousness; namely, that, in the midst of so many temptations, he steadily held on his way.

This verse may be explained in two ways. Some are of opinion that David declares how carefully he had studied uprightness among men; but I rather think that he celebrates the grace of God towards him, and, at the same time, vows his gratitude.
