“Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.”
King James Version (KJV)
12:38 We would see a sign - Else we will not believe this. #Matt 16:1|; Luke 11:16,29.
Mt 12:38 Master, we would see a sign from thee. Compare Mt 16:1 Lu 11:16,29. They had just seen a miracle, but demand another. Jesus never worked miracles to gratify human curiosity, or to secure popular applause.
