Here the Prophet tells us that he was sent to the people and to the priests, not so much to teach the messengers who came from distant lands, as to correct the vices of his own nation; for the Jews had then begun, according to their usual manner, to dissemble with God, and had glided, as it has elsewhere appeared, into many evil practices. And it appears evident, that God did not commit to Zechariah what the messengers might bring back to Chaldea; but that an occasion was taken to remind the Jews, that they were to look to themselves. It may have been the case, that the priests themselves and all the rest had begun to raise a controversy, “How is this? our brethren inquire, whether the fast is to be still observed:” and the opinions might have been various. But as this is doubtful, I leave it as such. We however see that the Prophet does not speak here respecting the captives, nor does he address to their messengers anything which they might convey to Chaldea, but turns his discourse to the priests and to the people. The sum of the whole is, that while the captives gave no mean testimony of their religion, God reproved the Jews, who had returned to their own country, for ingratitude, as they had already begun to pollute themselves.
