As for God - The declaration in this verse is suggested by the facts narrated in the previous verses. The contemplation of those facts leads the thoughts of the author of the psalm up to the Great Source of all these blessings, and to these general reflections on his character. “As for God,” that is, in respect to that Great Being, who has delivered me, his ways are all perfect; his word is tried; he is a shield to all those who trust in him.
His way is perfect - That is, his doings are perfect; his methods of administration are perfect; his government is perfect. There is nothing wanting, nothing defective, nothing redundant, in what he does. On the word perfect, see the note at Job 1:1.
The word of the Lord is tried - Margin, refined. The idea is, that his word had been tested as silver or any other metal is in the fire. The psalmist had confided in him, and had found him faithful to all his promises. Compare the note at Psalms 12:6. In a larger sense, using the phrase the “word of the Lord” as denoting the revelation which God has made to mankind in the volume of revealed truth, it has been abundantly tested or tried, and it still stands. It has been tested by the friends of God, and has been found to be all that it promised to be for support and consolation in trial; it has been tested by the changes which have occurred in the progress of human affairs, and has been found fitted to meet all those changes; it has been tested by the advances which have been made in science, in literature, in civilization, and in the arts, and it has shown itself to be fitted to every stage of advance in society; it has been tested by the efforts which men have made to destroy it, and has survived all those efforts.
It is settled that it will survive all the revolutions of kingdoms and all the changes of dynasties; that it will be able to meet all the attacks which shall be made upon it by its enemies; and that it will be an unfailing source of light and comfort to all future ages. If persecution could crush it, it would have been crushed long ago; if ridicule could drive it from the world, it would have been driven away long ago; if argument, as urged by powerful intellect, and by learning, combined with intense hatred, could destroy it, it would have been destroyed long ago; and if it is not fitted to impart consolation to the afflicted, to wipe away the tears of mourners, and to uphold the soul in death, that would have been demonstrated long ago. In all these methods it has been “tried,” and as the result of all, it has been proved as the only certain fact, in regard to a book as connected with the future - that the Bible will go down accredited as a revelation from God to the end of the world.
He is a buckler - Or, a shield, for so the original word means. See the note at Psalms 3:3.
