ISB ~ Hebrews 7 v11 - 19

God’s oath to reestablish the priesthood of Melchizedek (7:17) implies that the priesthood of Aaron was deficient and destined to pass away. The problem:its laws and liturgies were powerless to cleanse and perfect the worshiping People of God (7:19; 9:9-10; 10:1-4). For a similar line of reasoning, See note on Heb 8:7.
