“How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him;”
King James Version (KJV)
2:3 So great a salvation - A deliverance from so great wickedness and misery, into so great holiness and happiness. This was first spoken of (before he came it was not known) by Him who is the Lord - of angels as well as men. And was confirmed to us - Of this age, even every article of it. By them that had heard him - And had been themselves also both eye - witnesses and ministers of the word.
Heb 2:3 How shall we escape. How then, if this was true of the law, can we hope to escape if he neglect the message of the Son? So great salvation. Not a temporal, but an eternal salvation, the salvation of the gospel. Which at the first began to be spoken by the Lord. More especially after his death and resurrection when he bade his disciples go into all the world and preach the gospel to every creature. Which was confirmed unto us by them that heard [him]. If Paul was the writer of Hebrews he places himself in the position of the church, for elsewhere he tells us plainly that he received the gospel from the Lord himself. The apostles who had heard and seen the risen Christ first proclaimed his gospel publicly on Pentecost, an event evidently alluded to in this passage.
