Contradiction with Numbers 23:19
This verse says God does not lie or change His mind, while in 1 Kings 13:11, the prophet claiming to speak for God through a falsehood leads to a contradiction in the sense of divine truth being questioned.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with Deuteronomy 18:20
God states that any prophet who speaks lies in His name must die, whereas in 1 Kings 13:11, the old prophet lies yet continues to live and is not immediately punished as per this standard.
Deuteronomy 18:20: But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.
Contradiction with 1 Samuel 16:7
This verse emphasizes that God looks at the heart, while in 1 Kings 13:11, the old prophet's deception is not immediately apparent in the narrative, questioning divine insight into human heart and actions.
1 Samuel 16:7: But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for [the LORD seeth] not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart. [outward...: Heb. eyes]
Contradiction with Proverbs 12:22
Lying lips are an abomination to the Lord, but the old prophet's lie in 1 Kings 13:11 is not directly called out as such by God in the immediate text context.
Proverbs 12:22: Lying lips [are] abomination to the LORD: but they that deal truly [are] his delight.
Contradiction with Psalm 101:7
This verse states that deceitful individuals shall not dwell in God’s house, contrasting with the apparent acceptance or lack of immediate consequence for the old prophet’s deceit in 1 Kings 13:11.
Psalm 101:7: He that worketh deceit shall not dwell within my house: he that telleth lies shall not tarry in my sight. [shall not tarry: Heb. shall not be established]
