Psalm 30:1
30:1 A Psalm [and] Song [at] the dedication of the {a} house
     of David. I will extol thee, O LORD; {b} for thou hast
     lifted me up, and hast not made my foes to rejoice over me.

     (a) After Absalom had polluted it with most filthy
         fornication.
     (b) He condemns them for great ingratitude who do not
         praise God for his benefits.

Psalm 30:2
30:2 O LORD my God, I cried unto thee, and thou hast {c} healed
     me.

     (c) Restored from the rebellion of Absalom.

Psalm 30:3
30:3 O LORD, thou hast brought up my {d} soul from the grave:
     thou hast kept me alive, that I should not go down to the
     pit.

     (d) Meaning, that he escaped death most narrowly.

Psalm 30:4
30:4 Sing unto the LORD, O ye {e} saints of his, and give thanks
     at the remembrance of his holiness.

     (e) The word signifies them who have received mercy, and
         show mercy liberally to others.

Psalm 30:6
30:6 And in my {g} prosperity I said, I shall never be moved.

     (g) I put too much confidence in my quiet state as in
         Jeremiah 31:18, 2 Chronicles 32:24,25.

Psalm 30:7
30:7 LORD, by thy favour thou hast made my {h} mountain to stand
     strong: thou didst hide thy face, [and] I {i} was troubled.

     (h) I thought you had established me in Zion most surely.
     (i) After you had withdrawn your help, I felt my misery.

Psalm 30:9
30:9 What profit [is there] in my blood, when I go down to the
     pit?  Shall the {k} dust praise thee? shall it declare thy
     truth?

     (k) David means that the dead are not profitable to the
         congregation of the Lord here in the earth: therefore
         he would live to praise his Name, which is the end of
         man's creation.

Psalm 30:12
30:12 To the end that [my] {l} glory may sing praise to thee,
      and not be silent. O LORD my God, I will give thanks unto
      thee for ever.

      (l) Because you have preserved me that my tongue should
          praise you, I will not be unmindful of my duty.
