Read Hebrews 2:3 Using Other Translations
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;
how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard,
So what makes us think we can escape if we ignore this great salvation that was first announced by the Lord Jesus himself and then delivered to us by those who heard him speak?
