Judaism's occult Zohar (a wicked mysticism book from Judaism) pushes repent of sins salvationism heresy by falsely claiming that those who do not repent of their sins will burn in Hell forever:

"But those who cling to their sins and refuse to repent of them will in the end descend to Gehinnom and never come up again."

(Zohar, Noach 19: 150 [Link])

Also, the Zohar unbiblically claims that repenting of sins makes atonement for a person's sins- this is a damnable works salvationist heresy and false teaching of antichrist Kabbalah Judaism:

"...when they return to thee from their sins thou shalt be prepared to forgive their sins and make atonement for them. Hence at all times Repentance is close at hand to men, and when they repent of their sins it returns to God and makes atonement for all, and judgement is suppressed and all is put right.

(Zohar, Archrei Mot 41:245 [Link])
