Ps 123:2
123:2 Behold, as the eyes of {a} servants [look] unto the hand
      of their masters, [and] as the eyes of a maiden unto the
      hand of her mistress; so our eyes [wait] upon the LORD our
      God, until that he have mercy upon us.

      (a) He compares the condition of the godly, to servants
          who are destitute of all help, assuring that when all
          other help fails, God is always at hand and like

Ps 123:3
123:3 Have mercy upon us, O LORD, have mercy upon us: for we are
      {b} exceedingly filled with contempt.

      (b) He declares that when the faithful are so full that
          they cannot endure the oppression and scorning of the
          wicked any more, there is always help above, if with
          hungry desires they call for it.
