From merizō (to divide). One who divides or arbitrates — a judge or settler of disputes. Jesus refused to serve as a property divider between two brothers.
When a man asked Jesus to make his brother divide the inheritance, Jesus replied: 'Man, who appointed me a judge or an arbiter between you?' (Luke 12:14). Jesus refused to reduce His mission to settling property disputes. He came not to divide estates but to divide light from darkness, truth from error, the saved from the lost. Jesus' kingdom operates on an entirely different plane than human courts.
