Yahweh hardened the heart of Pharaoh

Here "heart" refers to the Pharaoh. His stubborn attitude is spoken of as if his heart was hard. See how you translated a similar phrase in Exodus 9:12. Alternate translation: "Yahweh caused Pharaoh to became more defiant" (See: rc://en/ta/man/translate/figs-synecdoche and rc://en/ta/man/translate/figs-metaphor)
