Psalms 4:2

O ye sons of men, i.e. princes and potentates, as this Hebrew phrase seems and is thought to signify, who are engaged with Saul or Absalom against me. Will ye turn my glory into shame? or, shall my glory be for a shame, i.e. be made by you matter of reproach and scorn? By his glory probably he means that high honour and royal majesty which God had either promised to him, or conferred upon him; wherein, when he was in great straits and dangers, they might possibly reproach him in some sort as this: Is this the man, whom God so highly loves, and honours, and will exalt, who now flees from one mountain or cave to another, who runs away to the Philistines, whom his own son hath banished out of the land? Is this the effect of his glorying and boasting of God's favour and promises? Love vanity, i.e. affect and pursue these courses and designs of opposing me and my kingdom, which you will certainly find to be vain, and to no purpose. Leasing or, lying; the same thing with vanity; these two words being promiscuously used, as Psalms 62:9. Only this seems to add some emphasis, and to intimate the fair hopes and promising probabilities of success which they had, and which aggravate their disappointment. Or by lying he may design those horrid calumnies, which the partisans either of Saul or Absalom had raised against him, and which they joined with their other endeavours to make him odious to all the people, and so the better to effect his ruin.
