John Gill Commentary Ezekiel 20:4

"Wilt thou judge them, son of man, wilt thou judge them? Cause them to know the abominations of their fathers;" — Ezekiel 20:4 (ASV)

Will you judge them, son of man ? &c.] Excuse them, patronise them, defend their cause, and plead for them? surely you will not; or rather, will you not reprove and correct them, judge and condemn them, for their sins and wickedness? this you ought to do:

will you judge [them] ? this is repeated, to show the vehemency of the speaker, and the duty of the prophet:

cause them to know the abominations of their fathers : the sins they committed, which were abominable in themselves, and rendered them abominable unto God, and what came upon them for them; by which they would be led to see the abominable evils which they also had been guilty of, in which they had imitated their fathers, and what they had reason to expect in consequence of them.
