Adoni-Zedek, the king of Jerusalem, was alarmed by the rapid expansion and success of the Israelites under Joshua's command. The total destruction of Ai and Jericho was a testament to the Israelites' military prowess and the divine support they received. The news that Gibeon, a large and influential city, had made peace with Israel and joined them as allies was particularly troubling for the surrounding kingdoms. Gibeon's decision to ally with Israel was strategic, ensuring their survival and protection. This alliance signified a shift in power dynamics in the region, as other city-states realized the growing threat posed by Israel's presence.
The verse highlights the themes of fear and political maneuvering as local kings, like Adoni-Zedek, began to strategize against the Israelites. It sets the stage for the coalition of kings who would soon unite against Joshua and the Israelites in an attempt to curb their influence. This narrative underscores the broader biblical themes of divine intervention and the fulfillment of God's promises to the Israelites, as they continued to conquer and settle in the Promised Land.
