Adam Clarke on Psalms 30:11

Thou hast turned - my mourning into dancing - Rather into piping. I have not prayed in vain. Though I deserved to be cut off from the land of the living, yet thou hast spared me, and the remnant of my people. Thou hast taken away my sackcloth, the emblem of my distress and misery, and girded me with gladness, when thou didst say to the destroying angel, when he stood over Jerusalem ready to destroy it: "It is enough, stay now thy hand;" 2Sam 24:16.
