Killed and thrown into Gehenna
This saying presupposes the threat to their lives that the disciples would face when they announced the coming of the reign of God to Israel (cf. Matt. 10:27). If they are killed by the Jewish authorities because of their witness, they have nothing more to fear because God will watch over them (12:6) and they will be vindicated when the Son of man receives the kingdom from the Ancient of Days (12:8-9).
