In an essay I wrote, in my addendum (1,a) I said the following:
"While the Mosaic/Sinai (non everlasting) OLD COVENANT, which was, figuratively, nailed to the CROSS, at JESUS' death in 33 AD, was broken, contributing to the devastation for the Jews, the Abrahamic covenant, at least for the circumcised Jew, one would surmise, was to be still in effect for one further week (66 AD thru 73 AD), even though 70 AD saw the end of SACRIFICE AND GRAIN OFFERING. The NEW COVENANT (everlasting) through Jesus, which superseded the Abrahamic covenant and which was to include the Gentiles (after the gospel was taken to them by Peter...Acts Ch. 10), and be a covenant to all showing true FAITH in Jesus and his RANSOM SACRIFICE (sacrificial death of Jesus, made in order to reconcile sinners to a holy God...Mark, 10:45), takes center stage, after 73 AD, particularly benefiting those who will ultimately rule with Christ (144,000). The OC was based on promises to God, and was non everlasting, whereas the NC is based on God's promises to us, and God's word lasts forever.
