Joe: Wow, so we're talking about Hebrews 8 now, what's this all about?

Bible Expert: Well, Hebrews 8 is mostly about the superiority of Jesus' priesthood over the Aaronic one. That's the one that was established by Moses.

Joe: So Jesus is better than Moses?

Bible Expert: Yes, Jesus' priesthood is superior because He is the mediator of a better covenant, which was established on better promises.

Joe: Better promises? What do you mean by that?

Bible Expert: Well, the covenant that Jesus mediates is a better covenant in that it promises forgiveness of sins and a better relationship between God and His people. The Aaronic priesthood only provided a means of forgiveness through animal sacrifices.

Joe: Interesting! So how did Jesus establish this better covenant?

Bible Expert: Well, Jesus established it through His death on the cross. He was the perfect, sinless sacrifice and offered His life as a payment for our sins.

Joe: Wow, that's pretty incredible. So what does Hebrews 8 say about Jesus' priesthood?

Bible Expert: It says that Jesus is the perfect High Priest who is able to save us from our sins, and that He mediates a better covenant between God and His people. It also says that Jesus' priesthood is eternal and unchangeable, and that He is the only mediator between God and man.
