Albert Barnes Commentary Ezekiel 12:21-28

"And the word of Jehovah came unto me, saying, Son of man, what is this proverb that ye have in the land of Israel, saying, The days are prolonged, and every vision faileth? Tell them therefore, Thus saith the Lord Jehovah: I will make this proverb to cease, and they shall no more use it as a proverb in Israel; but say unto them, The days are at hand, and the fulfilment of every vision. For there shall be no more any false vision nor flattering divination within the house of Israel. For I am Jehovah; I will speak, and the word that I shall speak shall be performed; it shall be no more deferred: for in your days, O rebellious house, will I speak the word, and will perform it, saith the Lord Jehovah. Again the word of Jehovah came to me, saying, Son of man, behold, they of the house of Israel say, The vision that he seeth is for many day to come, and he prophesieth of times that are far off. Therefore say unto them, Thus saith the Lord Jehovah: There shall none of my words be deferred any more, but the word which I shall speak shall be performed, saith the Lord Jehovah." — Ezekiel 12:21-28 (ASV)

As in Ezekiel 7, the nearness of the judgment is foretold.

Ezekiel 12:22.

The land of Israel generally refers to the land where the Israelites lived, whether at home or in exile. There was a prevalent disregard for the true prophets, which is always followed by recognizing false prophets. First, the true prophet is rejected because it is believed his prophecies fail.

Then people persuade themselves that if the prophecy is true, it concerns some distant time, and that the present generation does not need to concern itself with it. (Amos 6:3; Matthew 24:43; 1 Thessalonians 5:2; 2 Peter 3:4). Against both these delusions, Ezekiel is commissioned to protest, and so to lead the way to his condemnation of his countrymen for their blind reliance on false prophets.
