Psalms 63:11

But the king shall rejoice in God I, who am anointed to be king, and who shall actually be king when these my enemies are fallen by the sword. Every one that sweareth by him By the name of God, namely, in truth, and judgment, and righteousness, as it is expressed Jeremiah 4:2, that is, every sincere servant and worshipper of God that invokes his name, and makes him the object of his religious reverence and fear: all which is implied in swearing by him, as an oath taken, as in the presence of God, is an immediate appeal and solemn act of worship to him. Accordingly, swearing is often put for the whole worship of God, and swearers by him, for worshippers of him. See Isaiah 45:23, compared with Romans 14:16; Isaiah 65:16. Shall glory Shall rejoice in my deliverance and exaltation, both for their respect for the honour and service of God, which I shall advance, and for the benefits which all good men and the whole kingdom shall receive by my government: whereas, in Saul's time, the vilest men were exalted, good men oppressed and persecuted, and the whole kingdom groaned under his tyranny. But the mouth of them that speak lies That now make it their business to invent or spread slanderous reports concerning me and others of God's people; shall be stopped They shall be so silenced that they shall not have a word to say for themselves. He may mean also, that when he should be in power, he would severely restrain and punish such wicked practices. Apply this to Christ's enemies. Those that speak lies against him, who pervert the right ways of the Lord, and speak ill of his holy religion, their mouths will be stopped too, when the Lord shall come to reckon for all the hard speeches which ungodly sinners have spoken against him. Christ's second coming will be the everlasting triumph of all his faithful friends and followers, who may therefore now triumph in the believing hopes of it.
