Psalm 149:1
149:1 Praise ye the LORD. Sing unto the LORD {a} a new song,
      [and] his praise in the congregation of saints.

      (a) For his rare and manifold benefits bestowed on his
          Church.

Psalm 149:2
149:2 Let Israel rejoice in him that {b} made him: let the
      children of Zion be joyful in their {c} King.

      (b) In that they were preferred before all other nations,
          it was a new creation, and therefore Psalm 95:7
          they were called the sheep of God's hands.
      (c) For God as he is the creator of the soul and body, so
          will he that both two serve him, and that his people
          be continually subject to him, as to their most lawful
          king.

Psalm 149:5
149:5 Let the saints be joyful in glory: let them sing aloud
      upon their {d} beds.

      (d) He alludes to that continual rest and quietness which
          they should have if they would suffer God to rule
          them.

Psalm 149:7
149:7 {e} To execute vengeance upon the heathen, [and]
      punishments upon the people;

      (e) This is chiefly accomplished in the kingdom of Christ
          when God's people for just causes execute God's
          judgments against his enemies and it gives no liberty
          to any to avenge their private injuries.

Psalm 149:8
149:8 To bind {f} their kings with chains, and their nobles with
      fetters of iron;

      (f) Not only the people, but the kings who were their
          enemies should be destroyed.

Psalm 149:9
149:9 To execute upon them the judgment {g} written: this honour
      have all his saints. Praise ye the LORD.

      (g) By this God binds the hands and minds of all his to
          enterprise no farther than he appoints.
