Gone is the Joy of our Hearts: Eicha 5:14-15

(14) "The old men are gone from the gate, The young men from their music (Lamentations 5:14)": Rabbi Abba son of Rabbi Jeremiah said: "They stopped from their singing".

(15) "Gone is the joy of our hearts (Lamentations 5:15)": Rabbi Chisda said: "At first when there was fear of the Sanhedrin over Israel they did not speak an offensive thing in song, but when they abolished the Sanhedrin, they said offensive things in song". Rabbi Jose the son of Rabbi Avin in the name of Rabbi Chisda said: "At first when trouble came upon Israel they stopped their joy because of that, and when they abolished the Sanhedrin, they abolished singing from the banquet house, as it is said: "They drink their wine without song (Isaiah 24:9)". Since this and that have been abolished: "Gone is the joy of our hearts; our dancing is turned into mourning".
