The "book" of Hebrews was written to the Hebrew people also known as the twelve tribes of Israel (Jacob.)
Read it in that context and come to the knowledge of the truth.
Everything in Scripture having to do with salvation is of the Jews was given to them by God. God gave Israel His Word, spiritual gifts, ministries, and everything having to do with salvation.
But non-Hebrew Gentiles who were enemies of the Jews stole everything God gave to Abram the Hebrew and his seed. Including the kingdom of God and the kingdom of heaven and everything God gave to Abraham's seed through covenant and prophecies.
Gentiles have stolen it from Israel after Israel was destroyed by Gentiles and scattered throughout the Gentile lands.
But God will have the last word.
14 But when the husbandmen saw him, they reasoned among themselves, saying, This is the heir: come, let us kill him, that the inheritance may be ours.
15 So they cast him out of the vineyard, and killed him. What therefore shall the lord of the vineyard do unto them?
Lk 20:14–15.
He will utterly destroy them.
