Corresponding Greek / Hebrew Entries: There is no direct Hebrew equivalent for συμβασιλεύω, as the concept of co-reigning with the Messiah is more explicitly developed in the New Testament. However, related themes of kingship and ruling can be found in Hebrew words such as מָלַךְ (malak, Strong's Hebrew 4427), meaning "to reign" or "to be king."

Usage: This verb is used in the New Testament to describe the act of reigning together with someone, often in a spiritual or eschatological context.

Context: The Greek verb συμβασιλεύω (symbasileuō) appears in the New Testament to convey the concept of co-reigning or sharing in a reign. This term is derived from the preposition σύν (syn), meaning "with," and the verb βασιλεύω (basileuō), meaning "to reign" or "to rule as a king." The compound form suggests a joint participation in ruling authority or kingship.

In the New Testament, συμβασιλεύω is used to describe the believers' future role in reigning with Christ. This concept is rooted in the eschatological promise that those who endure and remain faithful will share in Christ's victorious reign. The idea of co-reigning emphasizes the intimate and participatory relationship between Christ and His followers, highlighting the honor and responsibility bestowed upon believers in the age to come.

Biblical Reference:
• 2 Timothy 2:12 (BSB): "if we endure, we will also reign with Him; if we deny Him, He will also deny us."

In this passage, the Apostle Paul encourages Timothy and the early Christians to persevere in their faith, with the assurance that enduring trials and remaining steadfast will result in the privilege of reigning with Christ. This promise serves as both a motivation for faithfulness and a reminder of the eternal rewards awaiting those who are united with Christ.
