God "arises" when He displays by some signal act His care for His people. That strong anthropomorphism sets forth the plain truth that there come crises in history, when causes, long silently working, suddenly produce their world-shaking effects. God has seemed to sit passive; but the heavens open, and all but blind eyes can see Him, standing ready to smite that He may deliver. When He rises to His feet; the enemy scatters in panic. His presence revealed is enough. The emphatic repetition of "before" in these verses is striking, especially when fully rendered,--from His face (ver. 1); from the face of the fire (ver. 2); from the face of God (ver. 2); before His face (vv. 3, 4). To His foes that face is dreadful, and they would fain cower away from its light; His friends sun themselves in its brightness. The same fire consumes and vivifies. All depends on the character of the recipients. In the psalm "the righteous" are Israel, the ideal nation; the "wicked" are its heathen foes; but the principle underlying the fervid words demands a real assimilation of moral character to the Divine, as a condition of being at ease in the Light. The "deserts" are, in consonance with the immediately following reminiscences, those of the Exodus. Hupfeld and those who discover in the psalm the hopes of the captives in Babylon, take them to be the waste wilderness stretching between Babylon and Palestine. But it is better to see in them simply a type drawn from the past, of guidance through any needs or miseries. Vv. 5, 6, draw out at length the blessed significance of the name Jah, in order to hearten to earnest desire and expectance of Him. They are best taken as in apposition with "Him" in ver. 4. Well may we exult before Him who is the orphans' father, the widows' advocate. There may be significance in the contrast between what He is "in His holy habitation" and when He arises to ride through the deserts. Even in the times when he seems to be far above, dwelling in the separation of His unapproachable holiness, He is still caring and acting for the sad and helpless. But when He comes forth, it is to make the solitary to dwell in a home, to bring out prisoners into prosperity. Are these simply expressions for God's general care of the afflicted, like the former clauses, or do they point back to the Exodus? A very slight change in the text gives the reading, "Makes the solitary to return home"; but even without that alteration, the last clause of the verse is so obviously an allusion to the disobedient, "whose carcasses fell in the wilderness," that the whole verse is best regarded as pointing back to that time. The "home" to which the people were led is the same as the "prosperity" into which the prisoners are brought--namely, the rest and well-being of Canaan; while the fate of the "rebellious" is, as it ever is, to live and die amidst the drought-stricken barrenness which they have chosen.
