113 Grk “They are like children sitting … and calling out … who say.”
114 ‘We played the flute for you, yet you did not dance …’ The children of this generation were making the complaint (see vv. 33–34) that others were not playing the game according to the way they played the music. John and Jesus did not follow “their tune.” Jesus’ complaint was that this generation wanted things their way, not God’s.
115 The verb ἐθρηνήσαμεν (ethrēnēsamen) refers to the loud wailing and lamenting used to mourn the dead in public in 1st century Jewish culture.
