Apocalypse Revealed #300
300. And a crown was given to him. This symbolizes a token of their combat.
A crown symbolizes a token of combat because in ancient times kings wore crowns into battle, as can be seen from historical accounts, and to some degree from 2 Samuel 1:10, where we read that a man said to David concerning Saul, that when Saul was about to die in battle, he took the crown upon his head and the armlets upon his arms. And from what is related about the king in Rabbah and David in 2 Samuel 12:29-30.
Moreover, because trials or temptations are the kind of spiritual battles which the martyrs endured, therefore they were given crowns as tokens of their combat (no. 103).
It is apparent from this that a crown here symbolizes a token of their combat, on which account the statement also follows, "and he went out conquering and to conquer."
Lamentations 2:4
4
He has bent his bow like an enemy, he has stood with his right hand as an adversary, Has killed all that were pleasant to the eye: In the tent of the daughter of Zion he has poured out his wrath like fire.
