The superscriptions of Psalms 42 and 44 specifically mention the sons of Korah.
Now, their forefather Korah presumptuously reached out for an office he did not have the right to, so Jehovah put Korah and his rebel forces to death. Korah’s sons, however, did not join in the rebellion and God did not hold them accountable for their father’s sin. Their loyalty to Jehovah resulted in their own lives being spared and by their faithfulness they and their descendants were blessed and honored with temple service. This is in line with what Ezekiel chapter 18 talks about individual responsibility, for example that “a son himself will bear nothing because of the error of the father” and “the soul that is sinning, it itself will die”, showing us that even if close family members are sinning, then Jehovah will not hold us accountable for what they do.
