Luke 11:29

And when the people were gathered thick together ,.... Upon this woman's lifting up her voice, and saying the things she did; or rather to see what sign he would give, which some had desired Luke 11:16

he began to say, this is an evil generation . The Alexandrian copy, two copies of Beza's, and the Vulgate Latin, and Arabic versions read, "this generation is an evil generation"; and also it was an "adulterous one", as is added in Matthew 12:39

they seek a sign ; for they had asked one of him, Luke 11:16

and there shall no sign be given it, but the sign of Jonas the prophet ; one like unto it: See Gill on Matthew 12:39
