EXPOSITION
A SHORT psalm in praise of unity and brotherly harmony. As Dr. Kay observes, "The preservation of this unity was the object of the selection of ONE place, to which the tribes should go up on pilgrimage three times a year." And the intercommunion with each other, which the pilgrimages fostered, was certainly one of the chief means by which a unity of feeling and sentiment was kept up among the scattered members of the nation century after century. The pilgrimages were to the Israelites what the meetings at the Olympic and ether games were to the Greeks—at once witnesses to a belief in ethnic unity, and a strong and efficient bond of union. This psalm was therefore admirably fitted for a "pilgrim-song," which it is allowed on all hands to have been, and must have greatly helped the various classes of pilgrims-the spiritual and secular authorities, the rich, the poor, the citizen, the peasant, and the widely divided members of the Great Diaspora—to feel themselves united with each other and with Jehovah.
