Sh'mot (Exo) 34:6-7

ADONAI passed before him and proclaimed: “YUD-HEH-VAV-HEH!!! Yud-Heh-Vav-Heh [ADONAI] is God, merciful and compassionate, slow to anger, rich in grace and truth; showing grace to the thousandth generation, forgiving offenses, crimes and sins; yet not exonerating the guilty, but causing the negative effects of the parents’ offenses to be experienced by their children and grandchildren, and even by the third and fourth generations.”
