Hebrews 2 - "How shall we escape if we neglect so great a salvation?" 2018

Heb 2:2
For if the word spoken through angels proved unalterable, and every transgression and disobedience received a just recompense,

The "word spoken through angels" is the Torah of Elohim. We are told this by both Stephen and Paul Acts 7:53, Gal. 3:19). Every transgression and disobedience received a just recompense. Torah is just in it's judgments, regardless of what Christianity teaches today. The next verse asks a rhetorical question.

Heb 2:3
how shall we escape if we neglect so great a salvation? After it was at the first spoken through the Lord, it was confirmed to us by those who heard,

This passage is better understood in conjunction with verse 2. "How shall we escape if we neglect so great a salvation?" If we neglect so great a salvation, there is no escape. We will perish because the judgments in the Torah condemn us since we have all sinned at one time or another. This message of salvation through Yeshua was spoken of by Yeshua Himself.

Mark 1:14-15 And after John had been taken into custody, Jesus came into Galilee, preaching the gospel of God, 15and saying, “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.”

Matt. 4:17 and they have no firm root in themselves, but are only temporary; then, when affliction or persecution arises because of the word, immediately they fall away.

Luke 19:10 “For the Son of Man has come to seek and to save that which was lost.”

And was confirmed by those who heard Him.

Acts 3:19-21 “Repent therefore and return, that your sins may be wiped away, in order that times of refreshing may come from the presence of the Lord; 20and that He may send Jesus, the Christ appointed for you, 21whom heaven must receive until the period of restoration of all things about which God spoke by the mouth of His holy prophets from ancient time.

Acts 17:30-31 “Therefore having overlooked the times of ignorance, God is now declaring to men that all everywhere should repent, 31because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead.”
The book of Hebrews makes several statements that sound like warnings. In this chapter he tells us to pay much closer attention to what we have heard or else we might drift from it. Messiah was not merely an angel or merely a man. He is the Word of Yahweh made flesh and dwelt among us.
