Pray for the peace of Jerusalem,.... This is said to the persons that solicited the psalmist to go into the house of the Lord; to the truly godly among the tribes that went thither to worship; to his brethren and companions, for whose sake he wished well to Zion; to praying souls, who should not be singular and selfish; not only pray for themselves, but for others; for all saints, and for the church of God in general; for Jerusalem, not merely literally considered; though as that was the metropolis of the nation, and many of them the psalmist addresses were inhabitants of it, it became them to seek and pray for the peace of it, their own peace being concerned in it; see Jer 29:7; but for the spiritual and heavenly Jerusalem, the church of God, and for the peace of it; that Christ, the Man, the Peace, the Peacemaker, who then was not come, might come; that the members of it might enjoy spiritual peace in their son is, and might have peace one with another, and be at peace with their enemies; and enjoy the abundance of peace and prosperity, which will be in the latter day; and will lie in freedom from persecution, in a destruction of antichrist and all the the enemies of the church; in the purity of Gospel truths and ordinances, and the spread of them; in numerous conversions of Jews and Gentiles; in the unity of the Lord's people in sentiment, worship, and affection; and in a large increase of spiritual light and holiness: all which should be earnestly prayed for by the well-wishers of the cause of Christ; see Isa 62:6.
There may be an allusion to the name of Jerusalem, which signifies "they shall see peace"; and it should be prayed for that they might.
