Thou hast turned my mourning into dancing for me

Thou hast turned my mourning into dancing for me;
  Thou hast put off my sackcloth;
Thou hast turned my mourning into dancing for me,
  And girded me with gladness;
To the end my glory may sing praise unto Thee,
  And not be silent.
O Lord my God, I will give thanks unto Thee forever.
