6
καὶ ἐποίησεν κύριος τὸ ῥῆμα τοῦτο τῇ ἐπαύριον καὶ ἐτελεύτησεν πάντα τὰ κτήνη τῶν αἰγυπτίων ἀπὸ δὲ τῶν κτηνῶν τῶν υἱῶν ισραηλ οὐκ ἐτελεύτησεν οὐδέν
Exodus 9:6
Arcana Coelestia # 7300
7300. 'And Pharaoh's heart was unyielding' means obstinacy. This is clear from the meaning of 'the heart being unyielding' as obstinacy, as above in 7272.
