I had pity for mine holy name - Render it: I “had” a pitiful regard to “Mine Holy Name.”
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.
SDA Bible Commentary (limited)
Volume 1-7
21. Pity for mine holy name. That is, He will act for the honor of His name. He will restore His people not merely for their sake, but for His own name’s sake.
