Parallel
Exodus 7:13
Swete's Septuagint · Berean Standard Bible
καὶ κατίσχυσεν ἡ καρδία Φαραώ, καὶ οὐκ εἰσήκουσεν αὐτῶν, καθάπερ ἐνετείλατο 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.
