Psalm 27:1
27:1 [A Psalm] of David. The LORD [is] my {a} light and my
     salvation; whom shall I fear? the LORD [is] the strength of
     my life; of whom shall I be afraid?

     (a) Because he was assured of good success in all his
         dangers and that his salvation was surely laid up in

Psalm 27:3
27:3 Though an host should encamp against me, my heart shall not

Psalm 27:4

     seek after; that I may dwell in the house of the LORD all
     the days of my life, to behold the beauty of the LORD, and
     to enquire in his temple.

     (c) The loss of country, wife and all worldly conveniences
         would not grieve me as much as this one thing, that I
         may not praise your name in the midst of the
         congregation.

Psalm 27:6
27:6 {d} And now shall mine head be lifted up above mine enemies

     unto the LORD.

          the most tender love of parents towards their
          children.

Psalm 27:12
27:12 Deliver me not over unto the {g} will of mine enemies: for
      false witnesses are risen up against me, and such as
      breathe out cruelty.

          Isaiah 38:11.

          never failed in his promises.
