Romans 8:38

8:38 For I am convinced that neither death, nor life, nor angels, nor heavenly rulers, nor things that are present, nor things to come, nor powers,

Romans 13:3

13:3 (for rulers cause no fear for good conduct but for bad). Do you desire not to fear authority? Do good and you will receive its commendation,

tn BDAG 138 s.v. ἀρχή 6 takes this term as a reference to angelic or transcendent powers (as opposed to merely human rulers). To clarify this, the adjective “heavenly” has been supplied in the translation. Some interpreters see this as a reference to fallen angels or demonic powers, and this view is reflected in some recent translations (NIV, NLT).
