1 Kings 13: New criterion to determine the authenticity of an oracle

The pericope of 1 Kgs 13 deserves to be re-examined through the prism of true/false prophecy, despite the objections of some scholars. The question is not so much why the prophet lied - thereby formulating a false prophecy - but rather how to explain the man of God's failure to recognize his confrère’s false prophecy. Why didn't the man of God, if truly assisted by God, discern that it was a lie? It may well be that the pericope of 1 Kgs 13 offers some answers to this question, providing a new kind of criterion for detecting a lie and, therefore, false prophecy.
