Ezekiel 18:4, 20

Behold (pay close attention), all souls are Mine; the soul of the father as well as the soul of the son is Mine. The soul who sins will die. [Rom 6:23]

The person who sins [is the one that] will die. The son will not bear the punishment for the sin of the father, nor will the father bear the punishment for the sin of the son; the righteousness of the righteous shall be on himself, and the wickedness of the wicked shall be on himself.
