שופטים, פרק ו׳, פסוק ל״ב

Following the destruction of the pagan altar, a powerful public declaration takes place. To mark a complete ideological shift and a clear break from idol worship, Joash gives his son Gideon a new name [מצודת דוד]. This title effectively becomes Gideon's second name [ביאור שטיינזלץ]. The name, Jerubbaal, acts as a direct challenge, meaning that the idol Baal should try to contend and fight with him [רש"י].

Assigning this name carries a deep educational and spiritual purpose. It is meant to publicly prove that the idol is entirely empty and powerless. By carrying this name, Gideon declares his open conflict with the idol, completely rejecting it while fully accepting the worship of God. This bold move fulfills a higher divine plan to pull the people away from idolatry through Gideon's actions. Breaking free from these false beliefs serves as a necessary preparation for the nation's promised rescue, as God could not save the people as long as they continued to put their faith in an idol [מלבי"ם].
