Hebrews 2:1-3; Hebrews 2:10

1 We must pay the most careful attention, therefore, to what we have heard, so that we do not drift away. 2 For since the message spoken through angels was binding, and every violation and disobedience received its just punishment, 3 how shall we escape if we ignore so great a salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him.
10 In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered.
