They leap upon the city; they run upon the wall; they climb up into the houses; they enter in at the windows like a thief.
It afterwards follows, Through the city shall they march; over the wall shall they run here and there; into houses shall they climb; through the windows shall they enter like a thief. The Prophet here shows that the Jews in vain trusted in their fortified cities, for the enemies would easily penetrate into them.
God executes the judgment written in the law upon His own professing people for their sins. Ministers must sound the trumpet from God's word to warn of sin's fatal consequences, though even Zion is not exempt if she provokes Him. The privilege of His people is to be warned, that they might make peace with Him before the judgment falls.
