The place doomed to destruction is Babylon; it is here called the gates of the nobles (v. 2), because of the abundance of noblemen's houses that were in it, stately ones and richly furnished, which would invite the enemy to come, in hopes of a rich booty. The gates of nobles were strong and well guarded, and yet they would be no fence against those who came with commission to execute God's judgments. Before his power and wrath palaces are no more than cottages. Nor is it only the gates of the nobles, but the whole land, that is doomed to destruction (v. 5); for, though the nobles were the leaders in persecuting and oppressing God's people, yet the whole land concurred with them in it.
