Not only does Jesus establish a new covenant, but there seems to be something deficient about the old one which is now "obsolete".

Hebrews 8 quotes a chunk from Jeremiah 31 (which we looked at in the previous episode), and so is an excellent follow-on. The author in this chapter seems to be making the argument that there was some "fault", or something deficient, with the old covenant. We ponder what this issue seems to have been, and indeed which "old covenant" is the focus here.
