Who hardened the Pharaoh's heart?

What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.

How critical scholarship weighs this: Leans toward 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 Exodus plague cycle uses three different idioms for the hardening of Pharaoh's heart, and the agency assigned shifts across the narrative. In a cluster of verses YHWH is the agent — "I will harden his heart" (4:21), "I will harden Pharaoh's heart" (7:3), "the LORD hardened the heart of Pharaoh" (9:12; 10:20, 27; 11:10; 14:8). In another cluster Pharaoh is the agent — "he hardened his heart" (8:15, 32), "he sinned yet more, and hardened his heart, he and his servants" (9:34). The retrospective summary at 1 Samuel 6:6 attributes the hardening to Pharaoh and the Egyptians. The theological problem is moral responsibility: if YHWH hardens Pharaoh's heart, his refusal and the consequent plagues are divinely caused, yet Pharaoh is punished for that refusal.

The Hebrew detail matters and partly underwrites the source-critical analysis. Three verbs appear: חָזַק (ḥazaq, "to strengthen, make firm"), כָּבֵד (kaved, "to make heavy/dull"), and קָשָׁה (qashah, "to make hard/stubborn"). Critical scholars (Propp, Baden) observe that the verbs cluster by source — the Priestly material favors ḥazaq, while the older epic strands favor kaved and qashah — and that the redactional blending of these strands produces the alternation of agency in the received text. The composite character of the cycle, rather than a single author's psychology of Pharaoh, best explains why divine and human hardening sit side by side.

The strongest harmonization, advanced by Archer, Kaiser, and Douglas Stuart in the New American Commentary, reads a chronological escalation: in the early plagues Pharaoh hardens his own heart, and only later does YHWH confirm and intensify that self-chosen obstinacy — a judicial "handing over" analogous to the pattern in Romans 1:24-28. On this reading Pharaoh bears responsibility because he initiates, and divine hardening is a ratification of a freely chosen course. The reading is attractive because the received order does show self-hardening prominent early (8:15, 32) and divine hardening concentrated later.

The reading nonetheless founders on the programmatic statements that precede any action by Pharaoh. At 4:21 and 7:3, before the first plague and before Pharaoh has refused anything, YHWH announces the plan: "I will harden his heart, that he shall not let the people go," and "I will harden Pharaoh's heart, and multiply my signs." The hardening is thus pre-announced and theologically pre-committed; it is the engine of the whole sequence, whose stated purpose is the maximal display of YHWH's power — "that I might shew these my signs before him" (10:1), "that the Egyptians may know that I am the LORD" (14:18). Terence Fretheim reads the divine hardening as integral to this purpose rather than as a late judicial response to prior self-hardening. The chronological-escalation harmonization must simply set aside 4:21 and 7:3, which is precisely where it fails. One may, with the Calvinist tradition and with Paul's own appeal to Pharaoh in Romans 9:17-18 ("whom he will he hardeneth"), affirm a compatibilist account in which God ordains the hardening and Pharaoh remains culpable — but that is a theological resolution layered over the text, not a reconciliation of the text's own conflicting attributions. As narrative, Exodus assigns the hardening now to YHWH, now to Pharaoh, and announces the divine causation from the outset.

Where the critical reading lands: genuine contradiction in agency, reflecting composite sources and an unresolved theological tension.
