When the Philistines heard the noise of the shout, they said, What means the noise of this great shout in the camp of the Hebrews? They understood that the ark of Yahweh was come into the camp.
The fact that the people shouted loudly when the ark arrived at Ebenezer from Shiloh (1 Samuel 4:5) may be another indication that they were hoping to duplicate the victory at Jericho (cf. Joshua 6:20). Likewise the response of the Philistines when they heard the cry recalls Rahab’s revelation of how the Canaanites feared Yahweh (Joshua 2:9-11). These allusions to the victory at Jericho contrast the Israelites’ present attitude toward God with what it had been at that earlier battle.
