Hebrews 2:2-4

²For if the word spoken through angels proved unalterable, and every transgression and disobedience received a just penalty, ³how will we escape if we neglect so great a salvation? After it was at the first spoken through the Lord, it was confirmed to us by those who heard, ⁴God also testifying with them, both by signs and wonders and by various miracles and by gifts of the Holy Spirit according to His own will.
