Song of degrees of David. This psalm was penned by David, as some think when all the tribes of Israel united and chose and anointed him king over them, 2Sa 5:1; but, according to others, when the rebellion of his son Absalom was quelled, and all the tribes of Israel strove who should first bring back the king, and show the greatest zeal and loyalty to him, 2Sa 19:9; Theodoret supposes it to be prophetic, and to have respect to the union of the tribes after the Babylonish captivity, who had been disunited in the times of Rehoboam, but now were no more two nations and kingdoms, but one; see Eze 37:16; and others carry it further still, even to the first times of the Gospel, when the Christians were of one heart and of one soul, Ac 4:32; it may indeed be applied to any community, civil or religious, that is in peace and unity: and no doubt the design of David was to promote peace and harmony among his subjects; and love and affection in his family, among his children, brethren one of another, and of Solomon; who was to be his heir and successor, and under whose government it would be well for them to live peaceably and quietly.
Kimchi and Ben Melech refer the psalm to the times of the Messiah, and take it to be a prediction of the peace and concord between the King Messiah and the priest, of which Zerubbabel and Joshua were types; see Zec 6:13.
The inscription of the Syriac version is,"it is said of Moses and of Aaron, who dwelt in the tabernacle, in the house of the Lord; and there is an intimation in it of the perfect people,''the Christians in Gospel times.
Ver. 1. Behold, how good and how pleasant [it is],.... Aben Ezra thinks the word thing should be supplied; the thing is what follows;for brethren to dwell together in unity: which the Targum interprets of Zion and Jerusalem, as two brethren; Aben Ezra of the priests; Kimchi of the King Messiah and the priest; and Jarchi, and Kimchi's father, of the Israelites; which is best of all, especially of those who are Israelites indeed; for this is not to be understood of all mankind, who are in some sense brethren, being all of one blood, and among whom peace is to be cultivated; nor merely of those of the same nation, under one and the same government, who should endeavour to live peaceably and quietly; nor of brethren in a strict natural state, who belong to the same family, and are of the same parents, and should be kindly affectioned one to another; but rather of such who are so in a spiritual sense, who have God for their fatherly adoption and regeneration, are related to Christ the firstborn among many brethren, and are members one of another, in the same church state; all which are a reason why they should love as brethren, and endeavour to keep the unity of the Spirit in the bond of peace, Mt 23:8 1Pe 2:17; and "to dwell together in unity"; even as one man, as if one soul actuated them all; it is not only to dwell and abide in the house of God, where they have all a name and a place; but to associate together there, to go up to the house of God in company, and with delight to join together in acts of religious worship; to serve the Lord with one consent, with one mind and mouth to glorify God, and to be of one accord, having the same love; and to do all kind and good offices one to another in the most hearty and cordial manner; serving each other in love, bearing one another's burdens, sympathizing with each other in all circumstances, forgiving each other offences committed, praying with one another, and building up each other in their most holy faith, stirring up one another to love and to good works: now this is both "good" and "pleasant"; it is good, as being according to the will of God, the new command of Christ; what evidences the truth of regeneration, and of being the disciples of Christ; what makes the communion of saints comfortable and edifying, and without which a profession of religion is good for nothing: and it is pleasant to God and Christ, to angels and men, to the ministers of the Gospel, and to all about them and in a connection with them; and it is this which makes any particular dispensation in time delightful and agreeable; as the first times of the Gospel, and the latter day glory, the Philadelphian church state, which has its name from brotherly love; yea, it will be the glory and delight of heaven.
Now this is ushered in with a note of attention and admiration, "behold", and with a note of exclamation, "how"; the psalmist pointing at some instance or instances of this kind, which were very amiable, and worthy of imitation; and suggesting that such a case is rare and wonderful, and inexpressibly good, profitable, and pleasant.
Gussetius renders it, "how good is the sabbatism of brethren, even gathered together"; for the exercise of religion, prayer, praise, &c. Ebr. Comment. p.
