Psalm 128:1
128:1 A Song of degrees. Blessed [is] every one that feareth
      the LORD; that walketh in his {a} ways.

      (a) God approves not our life, unless it is reformed
          according to his word.

Psalm 128:2
128:2 For thou shalt eat the labour of thine {b} hands: happy
      [shalt] thou [be], and [it shall be] well with thee.

      (b) The world esteems them happy who live in wealth and
          idleness but the Holy Spirit approves them best who
          live of the mean profit of their labours.

Psalm 128:3
128:3 Thy wife [shall be] as a fruitful vine by the sides of
      thine house: thy {c} children like olive plants round
      about thy table.

      (c) Because God's favour appears in no outward thing more
          than in the increase of children, he promises to
          enrich the faithful with this gift.

Psalm 128:5
128:5 The LORD shall {d} bless thee out of Zion: and thou shalt
      see the good of {e} Jerusalem all the days of thy life.

      (d) Because of the spiritual blessing which God has made
          to his Church, these temporal things will be granted.
      (e) For unless God blessed his Church publicly, this
          private blessing was nothing.
