Cyrill of Alexandria
They were enslaved by the Egyptians for four hundred thirty years, yet by divine grace, they were delivered from the house of bondage and the iron furnace, as it is written, signifying the harshness of the Egyptians.
But the Lord hath taken you and brought you out of the iron furnaces of Egypt, to make you his people of inheritance, as it is this present day.
וְאֶתְכֶם֙ לָקַ֣ח יְהוָ֔ה וַיּוֹצִ֥א אֶתְכֶ֛ם מִכּ֥וּר הַבַּרְזֶ֖ל מִמִּצְרָ֑יִם לִהְי֥וֹת ל֛וֹ לְעַ֥ם נַחֲלָ֖ה כַּיּ֥וֹם הַזֶּֽה׃
