Ps 113:1
113:1 Praise ye the LORD. {a} Praise, O ye servants of the LORD,
      praise the name of the LORD.

      (a) By this often repetition he stirs up our cold dullness
          to praise God, seeing his works are so wonderful, and
          that we are created for the same cause.

Ps 113:4
113:4 The LORD [is] high above all {b} nations, [and] his glory
      above the heavens.

      (b) If God's glory shines through all the world, and
          therefore of all ought to be praised, what great
          condemnation were it to his people, among whom chiefly
          it shines, if they should not earnestly extol his
          Name?

Ps 113:7
113:7 He raiseth up the poor out of the dust, [and] lifteth the
      {c} needy out of the dunghill;

      (c) By preferring the poor to high honour and giving the
          barren children, he shows that God works not only in
          his Church by ordinary means, but also by miracles.
