Jude 1:9
But, when the ruling angel Michael disputed with the devil over [the final disposal of] the body of Moses, [even] he did not dare to bring derogatory charges against him [i.e., the devil], but said, "May the Lord rebuke you." [Note: Some suggest that this account appeared in an apocryphal book, possibly "The Assumption of Moses"].

For our struggle is not [actually] against human beings, but against rulers and authorities and leaders of this world's darkness, and against the spiritual forces of evil in the heavenly realms.

1 Peter 3:22
He has [now] gone to heaven, and is [seated] at the right side of God, where the angels and [other] authorities and powers have been subjected to Him.

For we [really] wanted to come to you [and] I, Paul, [even tried to come] more than once, but Satan prevented us. [Note: This was probably accomplished through the influence of certain people or circumstances].
