Exodus 11:10
Rahlfs Septuagint (1935) · Berean Standard Bible
Μωυσῆς δὲ καὶ Ααρων ἐποίησαν πάντα τὰ σημεῖα καὶ τὰ τέρατα ταῦτα ἐν γῇ Αἰγύπτῳ ἐναντίον Φαραω ἐσκλήρυνεν δὲ κύριος τὴν καρδίαν Φαραω καὶ οὐκ ἠθέλησεν ἐξαποστεῖλαι τοὺς υἱοὺς Ισραηλ ἐκ γῆς Αἰγύπτου
Moses and Aaron did all these wonders before Pharaoh, but the LORD hardened (note: Or stiffened or strengthened) Pharaoh’s heart so that he would not let the Israelites go out of his land.
