Wisdom of Solomon 5:15
14 Because the hope of the ungodly is like thistledown carried by the wind, and like a light frost driven away by a storm; it is dispersed like smoke before the wind, and it passes like the remembrance of a guest who stays but a day. 15 But the righteous live forever, and their reward is with the Lord; the Most High takes care of them. 16 Therefore they will receive a glorious crown and a beautiful diadem from the hand of the Lord, because with his right hand he will cover them, and with his arm he will shield them. 17 The Lord will take his zeal as his whole armor, and will arm all creation to repel his enemies;
Revelation 2:10
9 ‘I know the distress you are suffering and your poverty (but you are rich). I also know the slander against you by those who call themselves Jews and really are not, but are a synagogue of Satan. 10 Do not be afraid of the things you are about to suffer. The devil is about to have some of you thrown into prison so you may be tested, and you will experience suffering for ten days. Remain faithful even to the point of death, and I will give you the crown that is life itself. 11 The one who has an ear had better hear what the Spirit says to the churches. The one who conquers will in no way be harmed by the second death.’
Notes and References
"... A crown of glory is a symbol of honor in the Hebrew Bible. In Psalm 8:5, humanity is crowned with glory and honor, as an indication of being only a little lower than angels. In 1QHa 27:25 the scoffing of an enemy is transformed into a crown of glory. It can also have an eschatological connotation. According to Wisdom of Solomon 5:15-16, “the righteous live forever, and their reward is with the Lord ... Therefore they will receive a glorious crown and a beautiful diadem from the hand of the Lord.” In Revelation 2:10, a crown of life is a reward for fidelity unto death ..."
