Albert Barnes Commentary 1 Peter 5:4

"And when the chief Shepherd shall be manifested, ye shall receive the crown of glory that fadeth not away." — 1 Peter 5:4 (ASV)

And when the chief Shepherd shall appear. The prince of the pastors—the Lord Jesus Christ. "Peter, in the passage above, ranks himself with the elders; here he ranks Christ himself with the pastors."—Benson. (See the notes on 1 Peter 2:25.)

Compare Hebrews 13:20.

You shall receive a crown of glory. A glorious crown or diadem. Compare 2 Timothy 4:8 (see the notes on this verse).

That fades not away. This is essentially the same word, though somewhat different in form, which occurs in 1 Peter 1:4. (See the notes on this verse.)

The word occurs nowhere else in the New Testament. Compare 1 Corinthians 9:25 (see the notes on this verse).
