That is true. They were broken off because of their unbelief, but you stand by your faith [as believers understanding the truth of Christ’s deity]. Do not be conceited, but [rather stand in great awe of God and] fear [Him];

For where there is a will and testament involved, the death of the one who made it must be established,

Do not be carried away by diverse and strange teachings; for it is good for the heart to be established and strengthened by grace and not by foods [rules of diet and ritualistic meals], which bring no benefit or spiritual growth to those who observe them.

having been deeply rooted [in Him] and now being continually built up in Him and [becoming increasingly more] established in your faith, just as you were taught, and overflowing in it with gratitude.

For to which of the angels did the Father ever say,

“You are My Son,
Today I have begotten (fathered) You [established You as a Son, with kingly dignity]”?

And again [did He ever say to the angels],

“I shall be a Father to Him
And He shall be a Son to Me”?

[and besides this evidence] God also testifying with them [confirming the message of salvation], both by signs and wonders and by various miracles [carried out by Jesus and the apostles] and by [granting to believers the] gifts of the Holy Spirit according to His own will.

But resist him, be firm in your faith [against his attack—rooted, established, immovable], knowing that the same experiences of suffering are being experienced by your brothers and sisters throughout the world. [You do not suffer alone.]

Since [as is well known] many have undertaken to compile an orderly account of the things which have been fulfilled among us [by God],

For this reason Moses has given you [God’s law regarding] circumcision (not that it originated with Moses, but with the patriarchs) and you circumcise a man [even] on the Sabbath.

In this way our testimony about Christ was confirmed and established in you,

For if Abraham was justified [that is, acquitted from the guilt of his sins] by works [those things he did that were good], he has something to boast about, but not before God.

But the man who stands firmly committed in his heart, having no compulsion [to yield to his daughter’s request], and has authority over his own will, and has decided in his own heart to keep his own virgin [daughter from being married], he will do well.

In the same way, after supper He took the cup, saying, “This cup is the new covenant [ratified and established] in My blood; do this, as often as you drink it, in [affectionate] remembrance of Me.”

This is what I mean: the Law, which came into existence four hundred and thirty years later [after the covenant concerning the coming Messiah], does not and cannot invalidate the covenant previously established by God, so as to abolish the promise.

and so we sent Timothy, our brother and God’s servant in [spreading] the good news of Christ, to strengthen and encourage you [exhorting, comforting, and establishing you] in regard to your faith,

so that He may strengthen and establish your hearts without blame in holiness in the sight of our God and Father at the coming of our Lord Jesus with all His saints (God’s people).

You too, be patient; strengthen your hearts [keep them energized and firmly committed to God], because the coming of the Lord is near.

For they [the gifts, sacrifices, and ceremonies] deal only with [clean and unclean] food and drink and various ritual washings, [mere] external regulations for the body imposed [to help the worshipers] until the time of reformation [that is, the time of the new order when Christ will establish the reality of what these things foreshadow—a better covenant].

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].

After you have suffered for a little while, the God of all grace [who imparts His blessing and favor], who called you to His own eternal glory in Christ, will Himself complete, confirm, strengthen, and establish you [making you what you ought to be].
