The midst of them.
Went on his way.”
αὐτὸς δὲ διελθὼν διὰ μέσου αὐτῶν ἐπορεύετο.
Luke uniquely said that nothing happened to Jesus. He said that Jesus passed through them (αὐτὸς δὲ διελθὼν) in their midst (διὰ μέσου αὐτῶν) and went on his way (ἐπορεύετο). No harm, no foul. They did not do anything to Jesus as he escaped from there, without saying how it happened.
