15 The joy of our heart is ceased; our dance is turned into mourning.
[AD 1274] Thomas Aquinas on Lamentations 5:15
Here reference is made to the exercise of joy: "The joy of our hearts has ceased, our dincing has been turned to mourning." As the propher Amos states: "I will turn your feasts into mourning, and all your songs into lamentations." (Amos: 8:10).
