'First' in the Bible

how will we escape [the penalty] if we ignore such a great salvation [the gospel, the new covenant]? For it was spoken at first by the Lord, and it was confirmed to us and proved authentic by those who personally heard [Him speak],

For we [believers] have become partakers of Christ [sharing in all that the Messiah has for us], if only we hold firm our newborn confidence [which originally led us to Him] until the end,

For though by this time you ought to be teachers [because of the time you have had to learn these truths], you actually need someone to teach you again the elementary principles of God’s word [from the beginning], and you have come to be continually in need of milk, not solid food.

who has no day by day need, like those high priests, to offer sacrifices, first of all for his own [personal] sins and then for those of the people, because He [met all the requirements and] did this once for all when He offered up Himself [as a willing sacrifice].

For if that first covenant had been faultless, there would have been no occasion for a second one or an attempt to institute another one [the new covenant].

When God speaks of “A new covenant,” He makes the first one obsolete. And whatever is becoming obsolete (out of use, annulled) and growing old is ready to disappear.

Now even the first covenant had regulations for divine worship and for the earthly sanctuary.

for this [first or outer tabernacle] is a symbol [that is, an archetype or paradigm] for the present time. Accordingly both gifts and sacrifices are offered which are incapable of perfecting the conscience and renewing the [inner self of the] worshiper.

For this reason He is the Mediator and Negotiator of a new covenant [that is, an entirely new agreement uniting God and man], so that those who have been called [by God] may receive [the fulfillment of] the promised eternal inheritance, since a death has taken place [as the payment] which redeems them from the sins committed under the obsolete first covenant.

So even the first covenant was not put in force without [the shedding of] blood.

then He said, “Behold, I have come to do Your will.” [And so] He does away with the first [covenant as a means of atoning for sin based on animal sacrifices] so that He may inaugurate and establish the second [covenant by means of obedience].

But remember the earlier days, when, after being [spiritually] enlightened, you [patiently] endured a great conflict of sufferings,

[looking away from all that will distract us and] focusing our eyes on Jesus, who is the Author and Perfecter of faith [the first incentive for our belief and the One who brings our faith to maturity], who for the joy [of accomplishing the goal] set before Him endured the cross, disregarding the shame, and sat down at the right hand of the throne of God [revealing His deity, His authority, and the completion of His work].
