Contradiction with Luke 23:32-33
While Mark 15:27 mentions two robbers being crucified with Jesus, Luke specifies the men as criminals but not explicitly as robbers.
Luke 23:32-33: And there were also two other, malefactors, led with him to be put to death.
Contradiction with Matthew 27:38
The same event is described, yet there is a critique over the labels used for those crucified with Jesus, as "thieves" instead of "robbers" could imply a broader range of crimes.
Matthew 27:38: Then were there two thieves crucified with him, one on the right hand, and another on the left.
Contradiction with John 19:18
John's account of the crucifixion mentions two others being crucified with Jesus but does not label them as robbers, implying a potential difference in their criminal charges.
John 19:18: Where they crucified him, and two other with him, on either side one, and Jesus in the midst.
