Psalm 30 A Song at the Dedication of the House of David
1 I will extol Thee, O Lord, for Thou hast drawn me up,
and hast not let my foes rejoice over me.
2 O Lord my God, I cried to Thee for help,
and Thou hast healed me.
3 O Lord, Thou hast brought up my soul from Sheol,
restored me to life from among those gone down to the Pit.
4 Sing praises to the Lord, O you His saints,
and give thanks to His holy name.
5 For His anger is but for a moment,
and His favor is for a lifetime.
Weeping may tarry for the night,
but joy comes with the morning.
6 As for me, I said in my prosperity,
“I shall never be moved.”
7 By Thy favor, O Lord,
Thou hadst established me as a strong mountain;
Thou didst hide thy face,
I was dismayed.
8 To Thee, O Lord, I cried;
and to the Lord I made supplication:
9 “What profit is there in my death,
if I go down to the Pit?
Will the dust praise Thee?
Will it tell of Thy faithfulness?
10 Hear, O Lord, and be gracious to me!
O Lord, be Thou my helper!”
11 Thou hast turned for me my mourning into dancing;
Thou hast loosed my sackcloth
and girded me with gladness,
12 that my soul may praise Thee and not be silent.
O Lord my God, I will give thanks to Thee for ever.
– Psalm 30
Commentary based on St. Thomas Aquinas
After the death of Saul, David took possession of Jerusalem, and there he built his home. It is customary that when someone enters a house, he makes a celebration. It could be said that at that time, Psalm 30 was sung by David himself, when he first entered that new house in order to dwell there.
This house of David is understood to be Christ who is the head and body of the Church. And this same house is called tabernacle.
A tabernacle is associated with those who struggle: and thus the present Church (the Church militant) is called a tabernacle. Rev 21:3: “Behold the tabernacle of God with men,”. A house is associated with those who rest: thus the Church awaits the rest of heaven. Ps 121 [:1: “We shall go into the house of the Lord.
In this Psalm, David recounts all the benefits for which he gives thanks. He also invites others to praise and thank God.
