Hebrews 2:2

2 The message that God spoke by angels was certainly powerful. God punished people when they did not obey the Law that he gave to Moses. In a completely right way he punished people who did anything wrong.

2:2The Bible says that an angel gave God's Law to Moses on Sinai mountain many years ago. See Exodus 19-20, Acts 7:38, 53 and Galatians 3:19.
