Charles Spurgeon Commentary Isaiah 63:17

"O Jehovah, why dost thou make us to err from thy ways, and hardenest our heart from thy fear? Return for thy servants` sake, the tribes of thine inheritance." — Isaiah 63:17 (ASV)

O Lord, why have you made us to err from your ways, and hardened our heart from your fear? Return for your servants' sake, the tribes of your inheritance. The people of your holiness.

Or, "Your holy people."
