Psalm 50:16

Verse 16. What hast thou to do to declare my statutes? etc. All the medieval writers teach us, even from the Mosaic law, concerning the leper, how the writer of this Psalm only put in words what those statutes expressed in fact. For so it is written: "The leper in whom the plague is, ... he shall put a covering upon his upper lip." As they all, following Origen, say: Let them who are themselves of polluted lips, take good heed not to teach others. Or, to take it in the opposite way, see how Isaiah would not speak to his people, because he was a man of polluted lips, and he dwelt among a people of polluted lips, till they had been touched with the living coal from the altar; and by that, as by a sacrament of the Old Testament, a sentence of absolution had been pronounced upon them. J. M. Neale.

Verse 16. (second clause). Emphasis is laid on the phrase, to declare God's statutes, which both denotes such an accurate knowledge of them as one may obtain by numbering them, and a diligent and public review of them. Properly speaking the word is derived from the Arabic, and signifies to reckon in dust, for the ancients were accustomed to calculate in dust finely sprinkled over tablets of the Abacus. Hermann Venema.

Verse 16. But unto the wicked God saith, What has thou to do ... to take my covenant into thy mouth? For whom is the covenant made but for the wicked? If men were not wicked or sinful what needed there a covenant of grace? The covenant is for the wicked, and the covenant brings grace enough to pardon those who are most wicked; why, then, doth the Lord say to the wicked, What hast thou to do to take my covenant unto thy mouth? Observe what follows, and his meaning is expounded: Seeing thou hatest to be reformed. As if God had said, You wicked man, who protects you sin, and holds it close, refusing to return and hating to reform; what hast thou to do to meddle with my covenant? Lay off thy defiled hands. He that is resolved to hold his sin takes hold of the covenant in vain, or rather he lets it go, while he seems to hold it. Woe unto them who sue for mercy while they neglect duty. Joseph Caryl.

Verse 16. When a minister does not do what he teaches, this makes him a vile person; nay, this makes him ridiculous, like Lucian's apothecary, who had medicines in his shop to cure the cough, and told others that he had them, and yet was troubled with it himself. With what a forehead canst thou stand in a pulpit and publish the laws of God, and undertake the charge of souls, that when thine own nakedness appears, when thy tongue is of a larger size than thy hands, thy ministry is divided against itself, thy courses give thy doctrine the lie; thou sayest that men must be holy, and thy deeds do declare thy mouth's hypocrisy; thou doest more mischief than a hundred others. William Fenner.
