[49:8] 1 tn Heb “their life.” Some emend the text to “his life,” understanding the antecedent of the pronoun as “brother” in v. 7. However, the man and brother of v. 7 are representative of the human race in general, perhaps explaining why a plural pronoun appears in v. 8. Of course, the plural pronoun could refer back to “the rich” mentioned in v. 6. Another option (the one assumed in the translation) is that the suffixed mem is enclitic. In this case the “ransom price for human life” is referred to an abstract, general way.
[49:8] 2 tn Heb “and one ceases forever.” The translation assumes an indefinite subject which in turn is representative of the entire human race (“one,” that refers to human beings without exception). The verb חָדַל (khadal, “cease”) is understood in the sense of “come to an end; fail” (i.e., die). Another option is to translate, “and one ceases/refrains forever.” In this case the idea is that the living, convinced of the reality of human mortality, give up all hope of “buying off” God and refrain from trying to do so.
