“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 ignore so great a salvation? This salvation was first announced by the Lord, and those who heard him have confirmed it to us — Warning 1 of Hebrews announces the rhetorical escalation: the Son himself announced the gospel; apostolic witnesses confirmed it. To neglect such a proclamation is to court inescapable judgment.
