The hypothesis of the Davidic authorship gives special force to the great assurance of ver. 7. The fugitive, in his rude shelter in the cave of Adullam, thinks of Jacob, who, in his hour of defenceless need, was heartened by the vision of the angel encampment surrounding his own little band, and named the place "Mahanaim," the two camps. That fleeting vision was a temporary manifestation of abiding reality. Wherever there is a camp of them that fear God, there is another, of which the helmed and sworded angel that appeared to Joshua is Captain, and the name of every such place is Two Camps. That is the sight which brightens the eyes that look to God. That mysterious personality, "the Angel of the Lord," is only mentioned in the Psalter here and in Psalm xxxv. In other places, He appears as the agent of Divine communications, and especially as the guide and champion of Israel. He is "the angel of God's face," the personal revealer of His presence and nature. His functions correspond to those of the Word in John's Gospel, and these, conjoined with the supremacy indicated in his name, suggest that "_the_ Angel of the Lord" is, in fact, the everlasting Son of the Father, through whom the Christology of the New Testament teaches that all Revelation has been mediated. The psalmist did not know the full force of the name, but he believed that there was a Person, in an eminent and singular sense God's messenger, who would cast his protection round the devout, and bid inferior heavenly beings draw their impregnable ranks about them. Christians can tell more than he could, of the Bearer of the name. It becomes them to be all the surer of His protection.
Just as the vow of ver. 1 passed into invocation, so does the personal experience of vv. 4-7 glide into exhortation. If such be the experience of poor men, trusting in Jehovah, how should the sharers in it be able to withhold themselves from calling on others to take their part in the joy? The depth of a man's religion may be roughly, but on the whole fairly, tested by his irrepressible impulse to bring other men to the fountain from which he has drunk. Very significantly does the psalm call on men to "taste and see," for in religion experience must precede knowledge. The way to "taste" is to "trust" or to "take refuge in" Jehovah. "Crede et manducasti," says Augustine. The psalm said it before him. Just as the act of appealing to Jehovah was described in a threefold way in vv. 4-6, so a threefold designation of devout men occurs in vv. 8-10. They "trust," are "saints," they "seek." Faith, consecration and aspiration are their marks. These are the essentials of the religious life, whatever be the degree of revelation. These were its essentials in the psalmist's time, and they are so to-day. As abiding as they, are the blessings consequent. These may all be summed up in one--the satisfaction of every need and desire. There are two ways of seeking for satisfaction: that of effort, violence and reliance on one's own teeth and claws to get one's meat; the other that of patient, submissive trust. Were there lions prowling round the camp at Adullam, and did the psalmist take their growls as typical of all vain attempts to satisfy the soul? Struggle and force and self-reliant efforts leave men gaunt and hungry. He who takes the path of trust and has his supreme desires set on God, and who looks to Him to give what he himself cannot wring out of life, will get first his deepest desires answered in possessing God, and will then find that the One great Good is an encyclopædia of separate goods. They that "seek Jehovah" shall assuredly find Him, and in Him everything. He is multiform, and His goodness takes many shapes, according to the curves of the vessels which it fills. "Seek ye first the kingdom of God ... and all these things shall be added unto you."
