I will sanctify my great name - By changing your hearts and your conduct, I shall show my hatred to vice, and my love to holiness: but it is not for your sakes, but for my holy name's sake, that I shall do you good in your latter days.
Matthew Henry
Concise Bible Commentary
The restoration of that people, being typical of our redemption by Christ, shows that the end aimed at in our salvation is the glory of God. The sin of a people defiles their land; renders it abominable to God, and uncomfortable to themselves. God's holy name is his great name; his holiness is his greatness, nor does any thing else make a man truly great.

23. Before their eyes. Several Hebrew manuscripts and the Syriac read “before your eyes.” Either reading makes good sense. The reading “your” brings out the important truth that it would be necessary for God first to be sanctified in the eyes of the people themselves by repentance and reformation, before He would be sanctified in the eyes of the heathen. His name had been “profaned among the heathen” by the unrepresentative lives of His professed people. The restoration of Israel would vindicate His name among the heathen. At that time it would clearly be demonstrated that Yahweh is not like the feeble gods of the heathen, but that He is all-powerful (see Deut. 28:58; Mal. 1:11).
