Revelation 2:21

she did not repent
Jezebel had been given time to recognize her wickedness and repent, but she would not. Here is introduced the pattern of the enemies of God throughout this book. Even in the face of clear evidence of God’s disapproval, those who have set their hearts against Him refuse to repent (Rev. Rev. 9:20-21+; Rev. 16:9-11+).

We often assume lack of repentance indicates a lack of understanding or the knowledge of evil. Yet Scripture indicates repentance has less to do with the head and more to do with the heart which is hardened toward God (Ex. Ex. 7:13, Ex. 7:23; Ex. 8:15, Ex. 8:19, Ex. 8:32; Ex. 9:34; Rom Rom. 2:5).
