Hebrews 1:1-7

1 God, who [a]at various times and in various ways spoke in time past to the fathers by the prophets, 2 has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the [b]worlds; 3 who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power, when He had [c]by Himself [d]purged [e]our sins, sat down at the right hand of the Majesty on high, 4 having become so much better than the angels, as He has by inheritance obtained a more excellent name than they.
The Son Exalted Above Angels

5 For to which of the angels did He ever say:

“You are My Son,
Today I have begotten You”?

And again:

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

6 But when He again brings the firstborn into the world, He says:

“Let all the angels of God worship Him.”

7 And of the angels He says:

“Who makes His angels spirits
And His ministers a flame of fire.”

God's Word was witnessed by the people who lived in those time periods.
