Psalm 142:1
142:1 Maschil of David; A Prayer when he was in the cave. I
      cried unto the LORD with my voice; with my voice unto the
      LORD did I {a} make my supplication.

      (a) David's patience and constant prayer to God condemns
          their wicked rage, who in their troubles either
          despair and murmur against God, or else seek other
          than God, to have relief in their miseries.

Psalm 142:5
142:5 I cried unto thee, O LORD: I said, Thou [art] my {b}
      refuge [and] my portion in the land of the living.

      (b) Though all means failed him, yet he knew that God
          would never forsake him.

Psalm 142:7
142:7 Bring my soul out of {c} prison, that I may praise thy
      name: the righteous shall {d} compass me about; for thou
      shalt deal bountifully with me.

      (c) For he was on all sides beset with his enemies as
          though he had been in a severe prison.
      (d) Either to rejoice at my wonderful deliverer, or to set
          a crown on my head.
