The glory that will redound to God by their repentance (v. 10): "They shall know that I am the Lord; they shall be convinced of it by experience, and shall be ready to own it, and that I have not said in vain that I would do this evil unto them, finding that what I have said is made good, and made to work for good, and to answer a good intention, and that it was not without just provocation that they were thus threatened and thus punished." Note, (1.) One way or other God will make sinners to know and own that he is the Lord, either by their repentance or by their ruin. (2.) All true penitents are brought to acknowledge both the equity and the efficacy of the word of God, particularly the threatenings of the word, and to justify God in them and in the accomplishment of them.
