Psalms 81

81:1-7 All the worship we can render to the Lord is beneath his excellences, and our obligations to him, especially in our redemption from sin and wrath. What God had done on Israel's behalf, was kept in remembrance by public solemnities. To make a deliverance appear more gracious, more glorious, it is good to observe all that makes the trouble we are delivered from appear more grievous. We ought never to forget the base and ruinous drudgery to which Satan, our oppressor, brought us. But when, in distress of conscience, we are led to cry for deliverance, the Lord answers our prayers, and sets us at liberty. Convictions of sin, and trials by affliction, prove his regard to his people. If the Jews, on their solemn feast-days, were thus to call to mind their redemption out of Egypt, much more ought we, on the Christian sabbath, to call to mind a more glorious redemption, wrought out for us by our Lord Jesus Christ, from worse bondage.

PSALM 81 This psalm was penned, as is supposed, not upon occasion of any particular providence, but for the solemnity of a particular ordinance, either that of the new-moon in general or that of the feast of trumpets on the new moon of the seventh month, Lev. 23:24; Num. 29:1. When David, by the Spirit, introduced the singing of psalms into the temple-service this psalm was intended for that day, to excite and assist the proper devotions of it. All the psalms are profitable; but, if one psalm be more suitable than another to the day and observances of it, we should choose that. The two great intentions of our religious assemblies, and which we ought to have in our eye in our attendance on them, are answered in this psalm, which are, to give glory to God and to receive instruction from God, to "behold the beauty of the Lord and to enquire in his temple;" accordingly by this psalm we are assisted on our solemn feast days, I. In praising God for what he is to his people (v. 1-3), and has done for them (v. 4-7). II. In teaching and admonishing one another concerning the obligations we lie under to God (v. 8–10), the danger of revolting from him (v. 11, 12), and the happiness we should have if we would but keep close to him (v. 13–16). This, though spoken primarily of Israel of old, is written for our learning, and is therefore to be sung with application.To the chief musician upon Gittith.

And here,I. The worshippers of God are excited to their work, and are taught, by singing this psalm, to stir up both themselves and one another to it, v. 1-3. Our errand is, to give unto God the glory due unto his name, and in all our religious assemblies we must mind this as our business. 1. In doing this we must eye God as our strength, and as the God of Jacob, v. 1. He is the strength of Israel, as a people; for he is a God in covenant with them, who will powerfully protect, support, and deliver them, who fights their battles and makes them do valiantly and victoriously. He is the strength of every Israelite; by his grace we are enabled to go through all our services, sufferings, and conflicts; and to him, as our strength, we must pray, and we must sing praise to him as the God of all the wrestling seed of Jacob, with whom we have a spiritual communion. 2. We must do this by all the expressions of holy joy and triumph. It was then to be done by musical instruments, the timbrel, harp, and psaltery; and by blowing the trumpet, some think in remembrance of the sound of the trumpet on Mount Sinai, which waxed louder and louder. It was then and is now to be done by singing psalms, singing aloud, and making a joyful noise. The pleasantness of the harp and the awfulness of the trumpet intimate to us that God is to be worshipped with cheerfulness and joy with reverence and godly fear. Singing aloud and making a noise intimate that we must be warm and affectionate in praising God, that we must with a hearty good-will show forth his praise, as those that are not ashamed to own our dependence on him and obligations to him, and that we should join many together in this work; the more the better; it is the more like heaven. 3. This must be done in the time appointed. No time is amiss for praising God (Seven times a day will I praise thee; nay, at midnight will I rise and give thanks unto thee); but some are times appointed, not for God to meet us (he is always ready), but for us to meet one another, that we may join together in praising Do. The solemn feast-day must be a day of praise; when we are receiving the gifts of God’s bounty, and rejoicing in them, then it is proper to sing his praises.II. They are here directed in their work. 1. They must look up to the divine institution which it is the observation of. In all religious worship we must have an eye to the command (v. 4): This was a statute for Israel, for the keeping up of a face of religion among them; it was a law of the God of Jacob, which all the seed of Jacob are bound by, and must be subject to. Note, Praising God is not only a good thing, which we do well to do, but it is our indispensable duty, which we are obliged to do; it is at our peril if we neglect it; and in all religious exercises we must have an eye to the institution as our warrant and rule: "This I do because God has commanded me; and therefore I hope he will accept me;" then it is done in faith. 2. They must look back upon those operations of divine Providence which it is the memorial of. This solemn service was ordained for a testimony (v. 5), a standing traditional evidence, for the attesting of the matters of fact.
