"She shall give to thine head an ornament of grace: a crown of glory shall she deliver to thee." (Proverbs 4:9)
There are five specific "crowns" mentioned in the New Testament as rewards for faithful service, presumably to be rewarded by Christ at His judgment seat (1 Corinthians 3:14). These are the "incorruptible" crown (1 Corinthians 9:25; 2 Corinthians 5:10); the "crown of righteousness" (2 Timothy 4:8); the "crown of rejoicing" (1 Thessalonians 2:19); "the crown of life" (James 1:12; Revelation 2:10); and lastly the "crown of glory" (1 Peter 5:4).
Although the crown of glory is mentioned only once in the New Testament, the phrase occurs four times in the Old Testament, each providing special insight into its character and scope. The first is Proverbs 4:9: "|Wisdom| shall give to thine head an ornament of grace: a crown of glory shall she deliver to thee."
The other three are, in order, as follows:
"The hoary head is a crown of glory, if it be found in the way of righteousness" (Proverbs 16:31).
"In that day shall the Lord of hosts be for a crown of glory, and for a diadem of beauty, unto the residue of his people" (Isaiah 28:5).
"Thou |probably a reference to the new Jerusalem| shalt also be a crown of glory in the land of the Lord, and a royal diadem in the hand of thy God" (Isaiah 62:3).
The one New Testament reference, in 1 Peter 5:4, is a wonderful promise to the faithful shepherds of each "little flock" (Luke 12:32) of believers: "And when the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away."
We do not know exactly what these crowns will be composed of, but when we see the Lord, we shall lay each of them before His throne (Revelation 4:10). HMM
