Jerome : (Verse 3.) Woe to the foolish prophets who follow their own spirit and see nothing. LXX: Woe to those who prophesy from their own heart and do not see at all, forsaking what is proposed by us and following their own spirit. Although the name of prophets, according to the rule of the Scriptures, is common to both the good and the bad, they differ in that the good prophets are said to be wise, while the bad ones are foolish and ignorant. The former is associated with ecclesiastical men, and the latter with all heretics, who, forsaking the spirit of God, follow their own spirit and prophesy not by divine inspiration but by their own heart. Hence, they see nothing. But whoever is wise, follows not the thoughts of his own heart, but the Spirit of God, according to what is mentioned in the earlier texts, that even animals and wheels followed the Spirit of God. And the prophet says: You shall walk after the Lord your God. And in another place: Lead me in the right path. And again: Your good Spirit shall lead me into the land. And for the people of God, the pillar of fire and the clouds were a guide in the wilderness. And Jeremiah speaks: I have not labored following you (Jerem. XVII, 16). But whoever of the heretics follows his own spirit, will stumble in darkness, and the blind will lead the blind into a pit? Although they may seem to see more in their mysteries, or rather orgies, than the ecclesiastical doctors, they do not see anything at all: because they have lost the sun of righteousness, and in vain imitate those who were previously called Seers, and to whom it is said: Go, you who see; turn back to the land of Judah; and in Bethel you will not prophesy (Amos VII, 12, 13). Therefore, the vision of Isaiah and Obadiah are placed in the titles. And the Lord commanded the apostles: Lift up your eyes and see (John 4:35). And the prophet earnestly prays: Open my eyes, and I will behold wondrous things out of your law (Psalms 119:18). — Commentary on Ezekiel Origen of Alexandria : In the same way that a saint prays with the Spirit and prays with understanding and sings with the spirit and sings with understanding, so the false prophet prophesies according to his own heart and follows not the Spirit of God but his own spirit. — HOMILIES ON Ezekiel 2:3
