One was on his right.
One was on his left.”
Καὶ σὺν αὐτῷ σταυροῦσιν δύο λῃστάς, ἕνα ἐκ δεξιῶν καὶ ἕνα ἐξ εὐωνύμων αὐτοῦ.
This is almost word for word in Matthew, chapter 27:38. Luke, chapter 23:39-43, has a dialogue between Jesus and the two bandits or criminals on either side of him, while he was hanging on the cross. Mark, Matthew, and John never mentioned any interaction of Jesus with either one of these two criminal bandits. In John, chapter 19:18, there was only a simple mention of two others crucified with him on either side of Jesus, presumably criminals. Mark said that there were two bandits or robbers crucified with Jesus (Καὶ σὺν αὐτῷ σταυροῦσιν δύο λῃστάς), one on his right side (ἕνα ἐκ δεξιῶν), and the other on his left side (καὶ ἕνα ἐξ εὐωνύμων).
