Repent before Hashem punishes: בתשובה שלמה לפניך Lifaniecha – before You (Tehilim 98:6).

Taz (O. C. 585:7) had a dream “blow shofar before Hashem makes it a bad year” — no shofar to start the year is bad. Repent before Hashem punishes; He wants us to repent before He must punish; Rambam rules that regarding repentance, confess before Hashem and it must be that Hashem is witness that it was real; Repentance; Yoma 86a repentance reaches Hashem’s throne (bypass angels; Shabbos 88b Moshe grabbed throne means the concept of repentance). Also: Rabbis cannot abolish a law permanently or one that is openly stated in Torah – marrying two women.
