PSALM 3.
David, although driven from his kingdom, and pressed down with utter despair of relief from every earthly quarter, ceases not to call upon God, and supports himself from his promise against the greatest terrors, against the mockery and cruel assaults of his enemies; and, finally, against death itself, which then forced itself upon his consideration. In the end of the psalm, he congratulates himself and the whole Church on the happy issue of all.
A Psalm of David, when he fled from Absalom his Son 1
How bitter David's sorrow was under the conspiracy of his own household against him, which arose from the treachery of his own son, it is easy for every one of us to conjecture from the feelings of nature. And when, in addition to this, he knew that this disaster was brought upon him by God for his own fault in having defiled another man's wife, and for shedding innocent blood, he might have sunk into despair, and been overwhelmed with anguish, if he had not been encouraged by the promise of God, and thus hoped for life even in death. From his making no allusion here to his sins, we are led to infer, that only one part of his prayers is comprised in this psalm; for as God punished him expressly on account of his adultery, and his wicked treachery towards Uriah, there can be no doubt that he was at first distressed with grievous and dreadful torments of mind. But after he had humbled himself before God, he took courage; and being well assured of having obtained forgiveness, he was fully persuaded that God was on his side, and knew that he would always preside over his kingdom, and show himself its protector. 2 But he, nevertheless, complained of his son, and of the whole faction involved in the conspiracy, because he knew that they wickedly rose up for the purpose of frustrating the decree of God. In like manner, if at any time God makes use of wicked and mischievous men, as scourges to chastise us, it becomes us first diligently to consider the cause, namely, that we suffer nothing which we have not deserved, in order that this reflection may lead us to repentance. But if our enemies, In persecuting us, rather 3 fight against God than against us, let the consideration of their doing so be immediately followed by the confident persuasion of our safety under the protection of him, whose grace, which he hath promised to us, they despise and trample under foot.
1 The inscription or title of the psalm refers it to the conspiracy of Absalom, and that the psalm refers to this is evident from the whole tenor of it. "But these titles are destitute of authority, as the careful reader of the Psalms will soon remark; they are to be regarded merely as marginal glosses of the Jews, but poor guides to the interpretation of Scripture." -- Fry's Translation and Exposition of the Psalms.
