1 Peter 5:4

And when the chief Shepherd shall be manifested, ye shall receive the crown of glory that fadeth not away.

The chief Shepherd ... is a reference to the Lord Jesus Christ who called himself the "Good Shepherd" (John 10:11). See more on this under 1 Peter 2:25.

Crown of glory that fadeth not away ... "The Greek words here mean literally an amaranthine wreath."[20] Amaranth is the name of a flower which, like our "immortelles", does not lose its color or form."[21] However, Peter here used the word as the best figure available for describing the eternal glory of the heavenly reward, thus providing another example of the extensive use of such figurative language throughout 1Peter. It is partially because of things like this that "Babylon" in 1 Peter 5:13 is understood as meaning "Rome."
