Rahlfs Septuagint (1935) · Berean Standard Bible
εἶπεν δὲ κύριος πρὸς Μωυσῆν πορευομένου σου καὶ ἀποστρέφοντος εἰς Αἴγυπτον ὅρα πάντα τὰ τέρατα ἃ ἔδωκα ἐν ταῖς χερσίν σου ποιήσεις αὐτὰ ἐναντίον Φαραω ἐγὼ δὲ σκληρυνῶ τὴν καρδίαν αὐτοῦ καὶ οὐ μὴ ἐξαποστείλῃ τὸν λαόν
The LORD instructed Moses, “When you go back to Egypt, see that you perform before Pharaoh all the wonders that I have put within your power. But I will harden (note: Or stiffen or strengthen) his heart so that he will not let the people go.
