Job 4:18 “Even in his servants he puts no trust, and his angels he charges with error.”
Job 25:5 “Behold, even the moon is not bright, and the stars are not pure in his sight.”
Michael Heiser summarizes these passages (Job 4:18, 15:15, and related ideas like 25:5) as showing that God’s heavenly host—His “holy ones” or angels—are fallible and imperfect, even though they serve Him. They are not inherently rebellious here but demonstrate free will and corruptibility, meaning God cannot fully trust them due to their potential for error or impurity, as seen post-fall in the biblical narrative.
He views this as evidence that divine beings, like humans, possess free will with inherent risk; only God is perfectly trustworthy. The “heavens not pure” parallels the holy ones’ imperfection, emphasizing proximity to God does not guarantee flawless obedience, supporting the broader unseen realm worldview of a divine council where members can fail.
