'Crown' in the Bible

Fear nothing that you are about to suffer. Be aware that the devil is about to throw some of you into prison, that you may be tested [in your faith], and for ten days you will have tribulation. Be faithful to the point of death [if you must die for your faith], and I will give you the crown [consisting] of life.

I am coming quickly. Hold tight what you have, so that no one will take your crown [by leading you to renounce the faith].

I looked, and behold, a white horse [of victory] whose rider carried a bow; and a crown [of victory] was given to him, and he rode forth conquering and to conquer.

Again I looked, and this is what I saw: a white cloud, and sitting on the cloud was One like the Son of Man, with a crown of gold on His head and a sharp sickle [of swift judgment] in His hand.
