Midrash for Sanhedrin 178:2
ונביא שעבר על דברי עצמו כגון עדו הנביא דכתיב (מלכים א יג, ט) כי כן צוה אותי וכתיב (מלכים א כ, ג) ויאמר לו גם אני נביא כמוך וכתיב (מלכים א יג, יט) וישב אתו וכתיב (מלכים א יג, כד) וילך וימצאהו אריה
OR A PROPHET WHO TRANSGRESSES HIS OWN WORDS. E.g., Iddo the prophet, as instanced by the following verses, [i] For so it was charged me by the word of the Lord [saying, Eat no bread, nor drink water, nor turn again by the same way that thou camest].<span class="x" onmousemove="('comment',' Ibid.
