Note 2 topic: figures-of-speech / metaphor

וַ⁠יֶּחֱזַ֤ק לֵב־פַּרְעֹה֙

(Some words not found in UHB: and,they_did so magicians_of Miʦrayim/(Egypt) by,enchantments_of,their and,it_was_strong heart_of Parˊoh's and=not listen to,them just=as he/it_had_said YHWH )

Pharaoh’s stubborn attitude is spoken of as if his heart were strong. If the heart is not the body part your culture uses to refer to a person’s will, consider using whichever organ your culture would use for this image. This is a neutral statement (it does not say that anyone caused him to be stubborn as many others in this part of the narrative do). See how you translated this in Exodus 7:13. Alternate translation: [Pharaoh was still defiant]

כַּ⁠אֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה

(Some words not found in UHB: and,they_did so magicians_of Miʦrayim/(Egypt) by,enchantments_of,their and,it_was_strong heart_of Parˊoh's and=not listen to,them just=as he/it_had_said YHWH )

Because Yahweh’s prediction precedes this event, some languages may need to place the reference to that prediction before the statement that it was fulfilled. See UST and how you translated this in 7:13, where the same sentence appears.
