Almost everyone associates Martin Luther with the book of Romans, particularly Romans 1:17, "The just shall live by faith" (KJV). However, we forget that Luther was converted not only by his study of Romans, but also by his study of the Psalms. Luther taught the Psalms for years and loved them very much. His favorite was Psalm 46. It is said of Luther that there were times during the dark and dangerous periods of the Reformation when he was terribly discouraged and depressed.
In verse 16 the pronouns "you" and "your" are masculine, which means that at this point the writer turns his attention back to the king, offering a kind of benediction or blessing on the marriage: "Your sons will take the place of your fathers" and "you will make them princes throughout the land." If we think of this in terms of the Messiah, it must refer to the "many sons" who will be brought into glory as a result of his fruitful union (Heb. 2:10, 13). As for the poet himself, "I will perpetuate your memory through all generations; therefore the nations will praise you for ever and ever," he says (v. 17).
The King's military victories. Though expressed in graphic battle language, we must remember that the victories of Jesus during his lifetime and in this present age are not military conquests but victories won on behalf of "truth, humility and righteousness" (v. 4). This was the way Jesus triumphed during his earthly ministry. From a purely physical point of view Jesus' enemies were victorious, since they succeeded in having him condemned and executed. But in terms of truth, humility and righteousness, Jesus won, since he upheld these characteristics in his person and conduct, even when he was being unjustly treated.
In a psalm unique among the Psalter, we also find a unique introduction (v. 1). In it the poet tells how the theme assigned to him as court poet has stirred his emotions. His is "a noble theme,” and he has been moved to pour all his considerable skill into the effort.
