Adam Clarke on Ezekiel 14:7

And cometh to a prophet - Generally supposed to mean a false prophet.

I the Lord will answer him by myself - I shall discover to him, by my own true prophet, what shall be the fruit of his ways. So, while their false prophets were assuring them of peace and prosperity, God's prophets were predicting the calamities that afterwards fell upon them. Yet they believed the false prophets in preference to the true. Ahab, about to engage with the Syrians, who had possession of Ramoth-Gilead, asked Micaiah, the prophet of the Lord, concerning the event; who told him he should lose the battle. He then inquired of Zedekiah, a false prophet, who promised him a glorious victory. Ahab believed the latter, marched against the enemy, was routed, and slain in the battle, 1Kgs 22:10, etc.
