1 Samuel 4:3
3 The Israelite soldiers returned to their tents. The leaders of Israel said to each other, ‘Why did the Lord let the Philistines win against us today? We should bring the Lord's Covenant Box here from Shiloh. We will take it with us into the battle. Then it will save us from our enemies.’
4:3The Covenant Box was where the Lord met with his people. So they thought that the Lord would be with them in the battle. See Exodus 25:17-21.
