Matthew 27:27 parallels this scene: soldiers lead Jesus into the Praetorium and gather the whole cohort.

John 18:28 describes Jesus being led to the Praetorium earlier, adding that Jewish leaders stayed outside to avoid defilement.

Matthew 20:19 is Jesus' prediction that Gentiles will mock and flog Him — fulfilled as Roman soldiers do so in Mark.

John 19:9 records Pilate questioning Jesus inside the Praetorium — the same setting where the soldiers mock Him in Mark.
