Psalms 18:43-45

Verse 43

The strivings of the people - Disaffections and insurrections among my own subjects, as in the revolt of Absalom, the civil war of Abner in favor of Ish-bosheth, etc.

The head of the heathen - ראש גוים rosh goyim, "the chief," or "governor, of the nations;" all the circumjacent heathen people; all these were subdued by David, and brought under tribute.

A people whom I have not known - The people whom he knew were those of the twelve tribes; those whom he did not know were the Syrians, Philistines, Idumeans, etc. All these served him, that is, paid him tribute.
Verse 44

As soon as they hear of me - His victories were so rapid and splendid over powerful enemies, that they struck a general terror among the people, and several submitted without a contest.

Strangers shall submit themselves unto me - Some translate this: "The children of the foreign woman have lied unto me." This has been understood two ways: My own people, who have sworn fealty to me, have broken their obligation, and followed my rebellious son. Or, The heathens, who have been brought under my yoke, have promised the most cordial obedience, and flattered me with their tongues, while their hearts felt enmity against me and my government. Nevertheless, even in this unwilling subjection I was secure, my police being so efficient, and my kingdom so strong.
Verse 45

The strangers shall fade away - בני נכר beney nechar, the same persons mentioned above. They shall not be able to effect any thing against me; יבלו yibbolu, "they shall fall as the leaves fall off the trees in winter."

And be afraid out of their close places - Those who have formed themselves into banditti, and have taken possession of rocks and fortified places, shall be so afraid when they hear of my successes, that they shall surrender at discretion, without standing a siege. Perhaps all these verbs should be understood in the perfect tense, for David is here evidently speaking of a kingdom at rest, all enemies having been subdued; or, as the title is, when the Lord Had delivered him from all his enemies.
