I. Unto the end. A psalm ofDavid. Though this heading is seen to be explained in the previous psalm, we are not reluctant to repeat briefly what we know is always salutary for us to hear. Unto the end denotes the Lord Christ; as Paul says: For the end of the law is Christ, unto justice to everyone that believeth. 1 Let us lift up our hearts to Him with all our strength, for in this psalm as by the voice of a herald we are forewarned that He comes as a Judge, fearful and almighty but also devoted and the object of great longing.
