ISB ~ Hebrews 8 v7

first covenant:The Mosaic covenant ratified at Sinai (Ex 19-24) and administered by the Levitical priests (Lev 1-16). Because the prophet Jeremiah later spoke of a “new covenant” (Heb 8:8), which the author calls a second covenant, he infers that the first is deficient and destined to pass away. For a similar line of reasoning, see note at Heb 7:11-19.
