Parallel
Exodus 8:15
Swete's Septuagint · Berean Standard Bible
ἰδὼν δὲ Φαραὼ ὅτι γέγονεν ἀνάψυξις, ἐβαρύνθη ἡ καρδία αὐτοῦ καὶ οὐκ εἰσήκουσεν αὐτῶν, καθάπερ ἐλάλησεν κύριος.
When Pharaoh saw that there was relief, however, he hardened (note: Or made heavy; also in verse 32) his heart and would not listen to Moses and Aaron, just as the LORD had said.
