Thou hast turned for me my mourning into dancing: thou hast put off my sackcloth, and girded me with gladness;
Thou hast turned ... - (cf. Psalms 30:5.)
Sackcloth - the robe symbolical of humble penitence, which David and the elders had assumed under God's visitation on the people, because of David's pride in numbering them; an undesigned coincidence with 1 Chronicles 21:16, "David and the elders of Israel ... clothed in sackcloth, fell upon their faces."
