What does 1 Samuel 7:10 mean?
This verse reveals just how close the Philistine army was to the gathered Israelite people at Mizpah. Context here suggests they were in the process of making their assault. The army was not merely close—they had begun the physical attack, itself, at the moment Samuel was offering a sacrifice (1 Samuel 7:9). At this same moment, however, God answers Samuel.That answer appears to have been in the form of a loud, ear-splitting thunder from heaven. This might have been "only" a sound, or a blast of pressure, or both. Whatever it was, exactly, this strikes the Philistines in the midst of their attack. The army is thrown into panic and chaos. This may have been a direct result of the thunder or because God sent confusion on them supernaturally. Unable to fight normally, the Philistine army was quickly defeated.
This wasn't the first time the Lord used thunder to announce His presence. Israel experienced the terror of it firsthand at Mount Sinai (Exodus 19:16). The Lord had promised to throw their enemies into confusion (Exodus 23:27), something He did during the days of Joshua (Joshua 10:10). Now the Lord has done so again. The Lord is more than capable of fighting for His people when they are faithful to Him.
