For there are no bands <chartsubbah> in their death: <maveth> but their strength <‘uwl> is firm. <bariy’> (Psalm 73:4 KJV)

Matthew Poole’s Commentary

Ver. 4.  There are no bands in their death; they are not dragged to death, neither by the hand and sentence of the magistrate, which yet they deserve; nor by any lingering and grievous torments of mind or body, which is the case of many good men; but they enjoy a sweet and quiet death, dropping into the grave, like ripe fruit from the tree, without ally violence used to them. Compare Job 5:26; 21:13.  

But their strength is firm, Heb. and their strength is fat, i.e. sound and good; the best of any thing being called fat in Scripture, as Ge 41:2; Da 1:15. And in their lifetime they have great ease, and health, and content, till they expire like a lamp, merely for want of moisture.

Thomas Scott

Verse 4: Wicked men often spend their lives without much sickness, and end them without great pain; while may pious persons scarcely know what health is, and die with great sufferings. Nay numbers of wicked are so hardened in presumptions that they die without terror or remorse. The original may be rendered, “They have no bands till their death.” They are not put in chains for execution like condemned criminals; but are let alone, till they are taken out of the world like other men. “There are neither pangs of body, nor remorse and terror of soul, in their death.” ( Bp. Hall.)
