In the beginning of this Psalm, Messiah, identifying Himself with the Remnant in the last days of their trouble, calls for the manifestation of Jehovah’s power in their behalf. But He does this with full and joyous anticipations, and therefore makes His usual vow of praise (Psa. 108:1-6). An answer to this comes immediately from the sanctuary, from the presence of God, or, it may be, according to the “holiness” of His counsels, to assure the suppliant that the Lord would, in due season, assert His kingdom (Psa. 108:7-9). This as immediately awakens Messiah’s zeal for the day of vengeance or the year of the redeemed (Isa. 63:1-5); for we know He is now expecting thus to tread down His enemies (Heb. 10:13). And then the whole closes with His again looking to Jehovah as the help in Jacob’s trouble, and with His confident anticipation of victory.
This Psalm is made up of the joyous portions of two previous Psalms (See Psa. 57; Psa. 60) which had both begun in sorrow and ended in joy. For there the soul of the believer had sowed in tears and reaped in joy; but here the double harvest is gathered, and the bosom of the worshipper is filled with sheaves. And, truly, joy is the thing that will remain. The sorrows shall be left behind, or remembered only to raise the gladness and give length and breadth to the praise.
This Psalm may happily follow the previous little volume on Resurrection (Psa. 103-107). For resurrection leads to joy and praise. As another once observed, Jesus Himself at the tomb of Lazarus wept, indulging the tears of all around Him; but at His own vacant tomb His way was changed, and in the liberty of resurrection Himself, He could say to His loved and loving disciple, “Woman, why weepest thou?”
