Numbers 23:19, 1 Samuel 15:29, Titus 1:2, and Hebrews 6:18 declare flatly that God cannot lie. Yet 1 Kings 22:23 has Yahweh personally putting a 'lying spirit' in the mouth of Ahab's prophets to lure him to his death, Ezekiel 14:9 has God say 'if a prophet is deceived, I the LORD have deceived that prophet,' and 2 Thessalonians 2:11 has God sending strong delusion so that people will believe a lie. The 'cannot lie' verses and the 'God deceives' verses can't both stand without redefinition.
Proposed answers
People have answered this in several ways; GEBible presents them as equal peers.
No, God cannot and does not lie.
God is not a man, that he should lie; neither the son of man, that he should repent. Numbers 23:19
The Strength of Israel will not lie nor repent. 1 Samuel 15:29
Thou art that God, and thy words be true. 2 Samuel 7:28
Thy word is true from the beginning. Psalm 119:160
In hope of eternal life, which God, that cannot lie, promised before the world began. Titus 1:2
It was impossible for God to lie. Hebrews 6:18
19God is not a man, that he should lie, nor a son of man, that he should repent. Has he said, and will he not do it? Or has he spoken, and will he not make it good?
18that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to take hold of the hope set before us.
10Then I said, “Ah, Lord Yahweh! Surely you have greatly deceived this people and Jerusalem, saying, ‘You will have peace;’ whereas the sword reaches to the heart.”
7Yahweh, you have persuaded me, and I was persuaded. You are stronger than I, and have prevailed. I have become a laughingstock all day. Everyone mocks me.
9“ ‘ “If the prophet is deceived and speaks a word, I, Yahweh, have deceived that prophet, and I will stretch out my hand on him, and will destroy him from among my people Israel.

How critical scholarship weighs this: Widely regarded as a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The cluster sets categorical denials against active divine deceptions. On one side: "God is not a man, that he should lie" (Numbers 23:19); "the Strength of Israel will not lie" (1 Samuel 15:29); "God, that cannot lie" (Titus 1:2); "it was impossible for God to lie" (Hebrews 6:18). On the other: Yahweh in the divine council asks "Who will entice Ahab?" and authorizes a volunteer spirit — "I will be a lying spirit in the mouth of all his prophets ... thou shalt entice him, and thou shalt also prevail; go forth, and do so" (1 Kings 22:20-22, paralleled in 2 Chronicles 18); "I the LORD have deceived that prophet" (Ezekiel 14:9); "God shall send them strong delusion, that they should believe a lie" (2 Thessalonians 2:11).
The traditional harmonization, developed by Augustine and Aquinas on the problem of concursus and codified in Geisler and Howe's When Critics Ask and Geisler's Systematic Theology, distinguishes God directly asserting falsehood — which the denial texts exclude — from God judicially commissioning deception as punishment upon those who have already chosen to reject the truth. On this reading the lying spirit, the deceived prophet of Ezekiel, and the Thessalonian delusion are all instruments of judgment visited on the already-guilty (Ahab's prophets; idolaters who "set up idols in their heart," Ezek 14:4; those who "received not the love of the truth," 2 Thess 2:10), not God speaking a personal falsehood. This is a genuinely coherent position and should not be dismissed as mere word-play; it tracks a recognizable moral distinction between deceiving an innocent and abandoning a hardened deceiver to his chosen lie. Frame articulates the Reformed version through concursus, in which God ordains the deception without being its proximate moral agent.
The weight of the critical objection falls on the verbs. The Hebrew of Ezekiel 14:9, pittiti (piel of patah, "to seduce, entice, deceive"), gives Yahweh the active causative — the same root that describes the seducer of a virgin in Exodus 22:16 (English) / 22:15 (Hebrew MT). 2 Thessalonians 2:11 has God as subject of pempei, "sends," with the delusion (energeian planēs) as direct object; this is causative, not bare permission. 1 Kings 22 does not depict permission either: Yahweh solicits a volunteer, ratifies the plan, and guarantees its success. So the harmonization cannot rest on softening these to permissive constructions; the grammar resists it. The defender must instead hold the line on definition — that commissioning a deceiving agent against the guilty is not "lying" in the sense the denial texts deny.
Three contextual observations frame the dispute. First, 1 Kings 22 belongs to a divine-council worldview, well documented by Patrick Miller and others, in which Yahweh presides over a heavenly assembly that deliberates and dispatches agents — a setting the later philosophical-theological tradition no longer shared. Second, the Micaiah episode is a prophetic vision-report whose point is to explain, after the fact, why the court prophets unanimously and wrongly predicted victory; it is a theodicy of false prophecy, not a treatise on divine veracity. Third, the "cannot lie" affirmations cluster in later strata — Titus and Hebrews are post-Pauline and articulate divine constancy in terms congenial to Hellenistic notions of an immutable, impassible deity, while Numbers 23:19 and 1 Samuel 15:29 pair "lie" with "repent / change his mind" and primarily assert the reliability of covenant promise, not a metaphysical incapacity for any deception. Brueggemann and Crenshaw stress that the older Israelite texts are comfortable with Yahweh employing deception within judgment, and Greenberg's treatment of Ezekiel 14:9 reads the deceived prophet as caught up in Yahweh's own act of judicial enticement rather than merely permitted to err.
The upshot: there is no flat formal contradiction once "lie" is restricted to direct assertion of falsehood to the innocent, because the deception texts uniformly target the already-guilty within a judgment frame. But that restriction is doing all the work, and it is contestable — Ezekiel's first-person "I have deceived" strains it, and the denial texts make no such carve-out.
Where the critical reading lands: disputed — real tension that turns on the contested scope of "lie" rather than on a demonstrable formal inconsistency.
