Shared ground
These closing lines underline a repeated pattern in the plague stories: a crisis hits, Pharaoh negotiates, the pressure lifts, and then he reverses course. The text explicitly says Pharaoh noticed the relief and then added to his wrongdoing rather than honoring his earlier words.
The passage also portrays hardening as both personal and social. Pharaoh hardens “he and his servants,” so this is not only a private inner change but a reinforced policy stance shared by the court.
Finally, the narrator anchors the outcome in a larger storyline: Pharaoh’s continued refusal matches what Yahweh had already said through Moses. That link frames the episode as part of an announced, unfolding sequence rather than a surprise turn.
Where interpretation differs
One question is how to relate v.34 (“Pharaoh…hardened his heart”) to v.35 (“the heart of Pharaoh was hardened”). Some readers take this as a deliberate shift from Pharaoh’s self-hardening to an implied divine hardening; others take v.35 as a summary restatement that does not specify who or what caused the hardening.
Another question is what “he sinned yet more” emphasizes. Some hear it as highlighting a specific betrayal of a promise made minutes earlier; others hear it as describing a repeated habit—Pharaoh’s established pattern becoming worse once the immediate danger passes.
Why the disagreement exists
The passage uses two ways of speaking about the same result: Pharaoh hardens, and Pharaoh’s heart “was hardened.” The second phrasing can be read either as simply describing the state of things, or as leaving room for a broader cause beyond Pharaoh’s choice. Also, the brief wording (“sinned yet more”) can point either to a concrete broken pledge in context or to the narrator’s general moral evaluation of Pharaoh’s ongoing resistance.
What this passage clearly contributes
These verses explicitly contribute (1) the moral evaluation that Pharaoh’s post-relief reversal is “sin” and an escalation, (2) the theme that relief can reveal true commitments, (3) the shared responsibility of Pharaoh and his officials in maintaining oppression, and (4) the storyline claim that events are aligning with Yahweh’s prior word through Moses (so the narrative stresses reliability of what was announced earlier).
