13 And I declare to him that I sentence his house to endless punishment for the iniquity he knew about—how his sons committed sacrilege at will—and he did not rebuke them.

3:13 I sentence his house to endless punishment
God tells Shmuel that He will punish Eli for failing to rebuke his sons, Chofni and Pinchas, for their immoral behavior while serving in their leadership roles at the Mishkan in Shilo. Through their actions, they profane the Mishkan and discourage people from making pilgrimages there. Consequently, Eli’s sons will be killed and there will be no one left to continue his family’s mantle of leadership. Instead, Shmuel will become the new prophet and leader of the people. He will act the way a true leader should, travelling among the people as an inspiring role model, bringing them closer to Hashem.
