Parallel
Exodus 7:13
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ κατίσχυσεν ἡ καρδία Φαραω καὶ οὐκ εἰσήκουσεν αὐτῶν καθάπερ ἐλάλησεν αὐτοῖς κύριος
Still, Pharaoh’s heart was hardened (note: Or stiffened or strengthened; also in verse 22), and he would not listen to them, just as the LORD had said.
