This compound verb intensifies the notion of shared suffering—not merely sympathizing but actively enduring hardship together. The passive form emphasizes receiving ill-treatment alongside another. In his catalogue of faith heroes, the Hebrews author notes that Moses chose to be 'mistreated with God's people' rather than enjoy sin's fleeting pleasures in Pharaoh's household. The verb captures Moses' deliberate solidarity with enslaved Israel, preferring shared oppression with God's people to privileged isolation. The prefix syn- ('with') emphasizes covenant community over individual comfort.
