Commentary on Ezekiel - Volume 2

He speaks of the exiled prophets, as will be evident from the context:
for among the captives there were those who assumed the name of God,
boasting themselves endowed with the prophetic spirit: but meanwhile
they intruded into the office, and then vainly boasted in their
deceptions. But the end which they proposed to themselves was to
promise the people a speedy return, and so to will the favor of the
multitude. For the captives were already almost broken-hearted by
weariness: and seventy years was a long period. When therefore they
heard of returning after three years, they easily suffered themselves
to be deceived by such blandishments. But although God is so vehemently
enraged against those impostors, it does not therefore follow that when
he charges them with their crime, he absolves the people, or even
extenuates their fault.
