tn The primary meaning of the Hebrew word עָוֹן (’avon) is “sin, iniquity.” But by metonymy it can refer to the “guilt” of sin, or to “punishment” for sin. The third meaning applies here. Just before this the Lord announces the punishment for Cain’s actions, and right after this statement Cain complains of the severity of the punishment. Cain is not portrayed as repenting of his sin.

tn Heb “great is my punishment from bearing.” The preposition מִן (min, “from”) is used here in a comparative sense.
