(5) And when the ark . . . came into the camp.--As far as we know, this was the first time since the establishment of the people in Canaan that the Ark had been brought from the permanent sanctuary into the camp. The shout of joy represented the confidence of the army that now the Ark, which had witnessed so many splendid victories of the chosen race, was among them, discomfiture was out of the question.

4:1-9 Israel is smitten before the Philistines. Sin, the accursed thing, was in the camp, and gave their enemies all the advantage they could wish for. They own the hand of God in their trouble; but, instead of submitting, they speak angrily, as not aware of any just provocation they had given him. The foolishness of man perverts his way, and then his heart frets against the Lord, Pr 19:3, and finds fault with him. They supposed that they could oblige God to appear for them, by bringing the ark into their camp. Those who have gone back in the life of religion, sometimes discover great fondness for the outward observances of it, as if those would save them; and as if the ark, God's throne, in the camp, would bring them to heaven, though the world and the flesh are on the throne in the heart.And when the ark of the covenant of the Lord came into the camp,.... Being brought thither by the men that carried it:

all Israel shouted with a great shout, so that the earth rang again; this they did as now sure of victory, because of the ark, and to give spirit and courage to each other to go forth to battle, and to strike a panic into their enemies.
