For the expounding of this psalm we may borrow a great deal of light from the apostle's discourse, Heb. 3 and 4, where it appears both to have been penned by David and to have been calculated for the days of the Messiah; for it is there said expressly (Heb 4:7) that the day here spoken of (Psa 95:7) is to be understood of the gospel day, in which God speaks to us by his Son in a voice which we are concerned to hear, and proposes to us a rest besides that of Canaan. In singing psalms it is intended, I. That we should "make melody unto the Lord;" this we are here excited to do, and assisted in doing, being called upon to praise God (Psa 95:1, Psa 95:2) as a great God (Psa 95:3-5) and as our gracious benefactor (Psa 95:6, Psa 95:7). II. That we should teach and admonish ourselves and one another; and we are here taught and warned to hear God's voice (Psa 95:7), and not to harden our hearts, as the Israelites in the wilderness did (Psa 95:8, Psa 95:9), lest we fall under God's wrath and fall short of his rest, as they did (Psa 95:10, Psa 95:11). This psalm must be sung with a holy reverence of God's majesty and a dread of his justice, with a desire to please him and a fear to offend him.
