Here is a short account of the issue of this battle.

I.Israel was smitten, the army dispersed and totally routed, not retiring into the camp, as before (Sa1 4:2) when they hoped to rally again, but returning to their tents, every man shifting for his own safety and making the best of his way home, despairing to make head any more; and 30,000 were slain in the field of battle, Sa1 4:10. Israel was put to the worse, 1. Though they had the better cause, were the people of God and the Philistines were uncircumcised; they stood up in necessary defence of their just rights and liberties against invaders, and yet they failed of success, for their rock had sold them. A good cause often suffers for the sake of the bad men that undertake it. 2. Though they had the greater confidence, and were the more courageous. They shouted, while the Philistines trembled, and yet, when God pleased so to order it, the Philistines' terrors were turned into triumphs, and Israel's shouts into lamentations. 3. Though they had the ark of God with them. External privileges will secure none that abuse them and do not live up to them. The ark in the camp will add nothing to its strength when there is an Achan in it.

II.The ark itself was taken by the Philistines; and Hophni and Phinehas, who it is likely kept close to it, and when it was in danger ventured far in the defense of it, because by it they got their living, were both slain, Sa1 4:11. To this sad even the Psalmist refers, Psa 78:61. 64, He delivered his strength into captivity, and his glory into the enemy's hands. Their priests fell by the sword. 1. The slaughter of the priests, considering their bad character, was no great loss to Israel, but it was a dreadful judgment upon the house of Eli. The word which God had spoken was fulfilled in it (Sa1 2:34): This shall be a sign unto thee, an earnest of the judgments threatened, thy two sons shall die both in one day, and so shall all the increase of thy house die in the flower of their age, v. 33. If Eli had done his duty, and put them, as polluted, from the priesthood (Neh 7:64), they might have lived, though in disgrace; but now God takes the work into his own hands, and chases them out of the world by the sword of the uncircumcised. The Lord is known by those judgments which he executeth. It is true the sword devours one as well as another, but these were waited for of the sword, marked for vengeance. They were out of the place; what had they to do in the camp? When men leave the way of their duty they shut themselves out of God's protection. But this was not all; they had betrayed the ark, by bringing it into danger, without a warrant from God, and this filled the measure of their iniquities. But, 2. The taking of the ark was a very great judgment upon Israel, and a certain token of God's hot displeasure against them. Now they are made to see their folly in trusting to their external privileges which they had by their wickedness forfeited them, and fancying that the ark would save them when God had departed from them. Now they are made to reflect, with the utmost regret, upon their own rashness and presumption in bringing the ark into the camp and so exposing it, and wish a thousand times they had left it where God had fixed it. Now they are convinced that God will not be prescribed to by vain and foolish men, and that though he has bound us to his ark he has not bound himself to it, but will rather deliver it into the hands of his sworn enemies than suffer it to be profaned by his false friends, and countenance their superstition. Let none think to shelter themselves from the wrath of God under the cloak of a visible profession, for there will be those cast into outer darkness that have eaten and drunk in Christ's presence.

Hophni and Phinehas were slain - They probably attempted to defend the ark, and lost their lives in the attempt.

And the ark of God was taken,.... By the Philistines; which was suffered partly as a punishment to the Israelites, for fetching it from the tabernacle without the will of God, and for their vain confidence in it; and partly that the Philistines might have an experiment of the power and might of God, as Procopius Gazaeus observes, by what they would suffer through having it among them; some have thought that this was an emblem of Christ being delivered into the hands of the Gentiles, and of the Gospel being translated from the Jews to them: and the two sons of Eli:

Hophni and Phinehas, were slain; which fulfilled the prophecy of the man of God, that they should both die in one day, Sa1 2:34. It is very probable they stood fast by the ark, and chose rather to die than to give it up freely; having received a charge from their father, that if the ark was taken, not to desire life, nor ever dare to come into his presence more, as Josephus (a) relates.

Let us fetch the ark of the covenant of the Lord out of Shiloh unto us--Strange that they were so blind to the real cause of the disaster and that they did not discern, in the great and general corruption of religion and morals (Sa1 2:22-25; Sa1 7:3; Psa 78:58), the reason why the presence and aid of God were not extended to them. Their first measure for restoring the national spirit and energy ought to have been a complete reformation--a universal return to purity of worship and morals. But, instead of cherishing a spirit of deep humiliation and sincere repentance, instead of resolving on the abolition of existing abuses, and the re-establishing of the pure faith, they adopted what appeared an easier and speedier course--they put their trust in ceremonial observances, and doubted not but that the introduction of the ark into the battlefield would ensure their victory. In recommending this extraordinary step, the elders might recollect the confidence it imparted to their ancestors (Num 10:35; Num 14:44), as well as what had been done at Jericho. But it is more probable that they were influenced by the heathenish ideas of their idolatrous neighbors, who carried their idol Dagon, or his sacred symbols, to their wars, believing that the power of their divinities was inseparably associated with, or residing in, their images. In short, the shout raised in the Hebrew camp, on the arrival of the ark, indicated very plainly the prevalence among the Israelites at this time of a belief in national deities--whose influence was local, and whose interest was especially exerted in behalf of the people who adored them. The joy of the Israelites was an emotion springing out of the same superstitious sentiments as the corresponding dismay of their enemies; and to afford them a convincing, though painful proof of their error, was the ulterior object of the discipline to which they were now subjected--a discipline by which God, while punishing them for their apostasy by allowing the capture of the ark, had another end in view--that of signally vindicating His supremacy over all the gods of the nations.
