Atonement Through Torah and Kindness
Torah learning
Hashem declared that the iniquity of the house of Eli would not be expiated with sacrifice or offering. The Gemara teaches that although it cannot be expiated with sacrifice or offering, it can be expiated with Torah study and with seeds of kindness. Even where one path of atonement is closed, Torah and acts of kindness remain open.
