17. O Jehovah! let me not be ashamed. In these words, the Psalmist continues his prayer, and to strengthen his hopes, he contrasts himself with his enemies; for it would have been more than absurd to permit those who by their wickedness so openly provoked the wrath of God to escape with impunity, and that one who was innocent and relied upon God should be disappointed and made a laughing-stock. Here, accordingly, we perceive what the Psalmist’s comparison implies. Moreover, instead of speaking of his hope or trust, he now speaks of his calling upon God, saying, I have called on thee; and he does this with good reason, for he who relies on the providence of God must flee to him with prayers and strong cries. To be silent in the grave, implies that death, when it befalls the ungodly, restrains and prevents them from doing farther injury. This silence is opposed both to their deceitful and treacherous devices, and to their outrageous insolence. In the very next verse, therefore, he adds, Let lying lips be put to silence, which, in my opinion, includes both their craftiness, and the false pretences and calumnies by which they endeavor to accomplish their designs, and also the vain boasting in which they indulge themselves. For he tells us that they speak with harshness and severity against the righteous, in pride and scorn; because it was their froward conceit, which almost always begets contempt, that made David’s enemies so bold in lying. Whoever proudly arrogates to himself more than is his due, will almost necessarily treat others with contempt.
