اَلْخُرُوجُ 11:10

وَكَانَ مُوسَى وَهَارُونُ يَفْعَلَانِ كُلَّ هَذِهِ ٱلْعَجَائِبِ أَمَامَ فِرْعَوْنَ، وَلَكِنْ شَدَّدَ ٱلرَّبُّ قَلْبَ فِرْعَوْنَ، فَلَمْ يُطْلِقْ بَنِي إِسْرَائِيلَ مِنْ أَرْضِهِ.

And Moses and Aaron did all these wonders before Pharaoh: and the LORD hardened Pharaoh’s heart, so that he would not let the children of Israel go out of his land.
