Extended Explanation of the Verse

Isaiah 54:17 is a promise of protection, vindication, and victory for God’s people. The verse begins with the assurance that no weapon formed against them will succeed.

For the Israelites, this promise was a source of hope that God would defend them against physical and spiritual threats, establishing them as His chosen people under His care.
