Hebrews 2:2-4

2:2 For if the message spoken through angels proved to be so firm that every violation or disobedience received its just penalty, 2:3 how will we escape if we neglect such a great salvation? It was first communicated through the Lord and was confirmed to us by those who heard him, 2:4 while God confirmed their witness with signs and wonders and various miracles and gifts of the Holy Spirit distributed according to his will.
