Hebrews 2 Bible study: So great a salvation

The chapter opens with Therefore: "Therefore we ought to pay greater attention to the things that were heard, lest perhaps we drift away." (2:1). Then it gives its reason in one long question that runs through three verses: "For if the word spoken through angels proved steadfast, and every transgression and disobedience received a just penalty, how will we escape if we neglect so great a salvation—which at the first having been spoken through the Lord, was confirmed to us by those who heard, God also testifying with them, both by signs and wonders, by various works of power, and by gifts of the Holy Spirit, according to his own will?" (2:2-4). The if is about "the word spoken through angels"; the question is about "so great a salvation". The letter says we here, and these notes don't say who the we are, or who "those who heard" were, beyond the letter's own words.

Genesis 3:15→leads toHebrews 2:14

The woman's offspring will bruise the serpent's head. Hebrews says Jesus took on flesh and blood "that through death he might bring to nothing him who had the power of death, that is, the devil." The New Testament doesn't quote 3:15, so this pairing is a reading Christians have long made, not a quotation; Protestants differ on whether the verse points to one person or a long struggle (see the honest question on 3:15).

Strong's: "to flow by, i.e. (figuratively) carelessly pass (miss)". "Therefore we ought to pay greater attention to the things that were heard, lest perhaps we drift away." (2:1): behind drift away is this one verb, and this is the only place the New Testament has it (counted in RP2018). The next verse gives the reason: "For if the word spoken through angels proved steadfast" (2:2).
