When thy people Israel shall be smitten down before the enemy,.... Beaten and routed, many slain, and others carried captive; which had been their case, and might be again, and was, though now a time of peace:
because they have sinned against thee; which always was the reason of their being given up into the hands of their enemies:
and shall turn again to thee; to thy worship, as the Targum, having fallen into idolatry, which was generally the case when they fell before their enemies:
and confess thy name; own him to be the true God, acknowledge his justice in their punishment, confess their sin, repent of it, and give him glory:
and pray and make supplication unto thee in this house; not the captives, unless it should be rendered, as it may, "toward this house" f; but those that escaped, or their brethren that went not out to battle, who should pray for them here.
f So Pool and Patrick.
