Ibrani 5:9

[9:15]  ¹ tn The Greek word μεσίτης (mesith", “mediator”) in this context does not imply that Jesus was a mediator in the contemporary sense of the word, i.e., he worked for compromise between opposing parties. Here the term describes his function as the one who was used by God to enact a new covenant which established a new relationship between God and his people, but entirely on God’s terms.

[9:15]  ² tn Grk “the promise of the eternal inheritance.”

[9:15]  ³ tn Grk “a death having occurred.”
