JFB : Psalms 87

      @Ps 87:1-7. This triumphal song was probably occasioned by the same event as the forty-sixth [see on Ps 46:1, title]. The writer celebrates the glory of the Church, as the means of spiritual blessing to the nation.

      1. His--that is, God's
      foundation--or, what He has founded, that is, Zion (@Isa 14:32).
      is in the holy mountains--the location of Zion, in the wide sense, for the capital, or Jerusalem, being on several hills.

      2. gates--for the enclosures, or city to which they opened (@Ps 9:14 122:2; compare @Ps 132:13,14).

      3. spoken of thee--or, "in thee," that is, the city of God (@Ps 46:4 48:2).

      4. This is what is spoken by God.
      to them . . . me--literally, "for My knowers," they are true worshippers (@Ps 36:10 Isa 19:21). These are mentioned as specimens.
      this--that is, nation
      was born there--Of each it is said, "This was born," or is a native of Zion, spiritually.

      5. The writer resumes--
      This and that man--literally, "man and man," or many (@Ge 14:10 Ex 8:10,14), or all (Isa 44:5 Ga 3:28).
      the highest . . . her--God is her protector.

      6. The same idea is set forth under the figure of a register made by God (compare @Isa 4:3).

      7. As in a great procession of those thus written up, or registered, seeking Zion (@Isa 2:3 Jer 50:5), "the singers" and "players," or pipers, shall precede.
      all my springs--So each shall say, "All my sources of spiritual joy are in Thee" (@Ps 46:4 84:6).
