For what the law was not able to do [for mankind], since it was [too] weak [to deliver them from condemnation] because fleshly people [were unable to obey it perfectly], God condemned sin in the flesh [i.e., sin was declared evil and its power over man broken]. God did this by sending His own Son in a body like sinful man's, and to destroy sin,

Hebrews 7:11-12

So, if perfection [i.e., a right relationship with God] could have been attained through the Levitical priesthood, (for under it people had received the law of Moses), what further need would there have been for another priest to arise, according to the order of Melchizedek, who was not considered "according to the order of Aaron"?

[That Tabernacle] is symbolic of the present time, [indicating] that both gifts and [animal] sacrifices, which are offered [by the priests], are not able to give the worshiper a clear conscience

Hebrews 10:1-9

For the law of Moses was [only] a foreshadow of the good things that [were] to come [i.e., in the Messianic age], not the exact image of those things. It can never, by the same sacrifices, continually offered year after year, make [morally] perfect those who draw near [to God in worship].

Hebrews 13:9

Do not continue to be swept off your course by all kinds of strange teachings. For it is good for your hearts to be strengthened by God's unearned favor [upon you] and not by [keeping regulations about] foods, which do not benefit those who observe them.
