'Afraid' in the Bible

But chiefly them that walk after the flesh in the lust of uncleanness, and despise government. Presumptuous are they, selfwilled, they are not afraid to speak evil of dignities.

Being bold and arrogant, they are not afraid to slander glorious beings. Yet even angels, although they are greater in strength and power, do not bring a slanderous accusation against them from the Lord.
