Parable of the assassin
The Parable of the [Wise] Assassin (also known as the Parable of the Killer), is a parable attributed to Jesus. However, it appears in none of the Canonical gospels of the New Testament but only in the non-canonical Gospel of Thomas. According to the Gospel of Thomas 98 Jesus said:
The kingdom of the father is like a certain man who wanted to kill a powerful man. In his own house he drew his sword and stuck it into the wall in order to find out whether his hand could carry through. Then he slew the powerful man.
