Psalm 50:16

But unto the wicked God saith, What hast thou to do to declare my statutes, or that thou shouldest take my covenant in thy mouth?

But unto the wicked God saith,.... By whom are meant, not openly profane sinners; but men under a profession of religion, and indeed who were teachers of others, as appears from the following expostulation with them: the Scribes, Pharisees, and doctors among the Jews, are designed; and so Kimchi interprets it of their wise men, who learnt and taught the law, but did not act according to it. It seems as if the preceding verses respected the truly godly among the Jews, who believed in Christ, and yet were zealous of the law; and retained legal sacrifices; as such there were, Acts 21:20; and that these words, and what follow, are spoken to hypocrites among them, who sat in Moses's chair, and said, and did not; were outwardly righteous before men, but inwardly full of wickedness, destitute of the grace of God and righteousness of Christ;

What hast thou to do to declare my statutes; the laws of God, which were given to the people of Israel; some of which were of a moral, others of a ceremonial, and others of a judicial nature; and there were persons appointed to teach and explain these to the people, as the priests and Levites: now some of these were abrogated, and not to be declared at all in the times this psalm refers to; and as for others, those persons were very improper to teach and urge the observance of them, when they themselves did not keep them; and especially it was wrong in them to declare them to the people, for such purposes as they did, namely, to obtain life and righteousness by them;

or that thou shouldest take my covenant in thy mouth? which is to be understood, not of the covenant of works made with Adam, and now broke; nor of the pure covenant of grace, as administered under the Gospel dispensation, of which Christ is the Mediator, and the Gospel a transcript, since both were rejected by these persons; but the covenant at Mount Sinai, which was a typical one; and being in some sense faulty, was now antiquated, and ought to have ceased; and therefore these men are blamed for taking it in their mouths, and urging it on the people: and besides, they had no true sight of and faith in the thing exhibited by it; and moreover were not steadfast, nor did they continue in it, like their fathers before them, Psalms 78:37 Hebrews 8:7.
