Jude 1:6 And I remind you of the angels who did not stay within the limits of authority, Hebrews 9:28: so also Christ was offered once for all time as a sacrifice to take away the sins of many people.

Jude 1:6 And I remind you of the angels who did not stay within the limits of authority God gave them but left the place where they belonged. God has kept them securely chained in prisons of darkness, waiting for the great day of judgment.  

Hebrews 9:28: so also Christ was offered once for all time as a sacrifice to take away the sins of many people. He will come again, not to deal with our sins, but to bring salvation to all who are eagerly waiting for him.
