1 Samuel 4:3

When the people were come into the camp. Before the battle Israel had entrenched itself, so that upon its defeat it had a place capable of defence into which to retire. We find also that their communications were open, so that they could send to Shiloh. The army is called the people because battles were not fought in those days by men specially trained, but by all the inhabitants of the country of the proper age. The question, Wherefore hath Jehovah smitten us? expresses surprise. The elders had evidently expected victory, and therefore the domination of the Philistines could not have been so complete as it certainly was in the days of Samson. There must have been an intermediate period of successful warfare during which Eli had been their leader. Let us fetch the ark of the covenant of Jehovah. This, the remedy suggested by the elders, was to employ their God as a talisman or charm. The ark was the symbol of Jehovah's presence among them, and of their being his especial people, and by exposing it to danger they supposed that they would compel their God to interfere in their behalf. They would have done right in appealing to their covenant relation to Jehovah; and had they repented of the sins which had grown up among them, fostered by the evil example of Eli's sons, he would have shown them mercy. But for God to have given Israel the victory because of the presence of his ark in their camp would have been to overthrow all moral government, and would have insured their spiritual ruin as inevitably as would the granting to any order of men now the power of working miracles or of infallibly declaring the truth.
