David
Psalm 40:5KJV·superscription

Many, O LORD my God, are thy wonderful works which thou hast done, and thy thoughts which are to us-ward: they cannot be reckoned up in order unto thee: if I would declare and speak of them, they are more than can be numbered.

John Calvin Reformed

PSALM 40 David, being delivered from some great danger, and it may be, not from one only, but from many, extols very highly the grace of God, and by means of this, his soul is filled with admiration of the providence of God, which extends itself to the whole human race.

C.H. Spurgeon Reformed Baptist

Many, O Lord my God, are thy wonderful works which thou hast done. Creation, providence, and redemption, teem with wonders as the sea with life. Our special attention is called by this passage to the marvels which cluster around the cross and flash from it.

Matthew Henry Presbyterian

In these verses we have, I. The great distress and trouble that the psalmist had been in. He had been plunged into a horrible pit and into miry clay (Psa 40:2), out of which he could not work himself, and in which he found himself sinking yet further.
