اَلْخُرُوجُ 4:21

وَقَالَ ٱلرَّبُّ لِمُوسَى: «عِنْدَمَا تَذْهَبُ لِتَرْجِعَ إِلَى مِصْرَ، ٱنْظُرْ جَمِيعَ ٱلْعَجَائِبِ ٱلَّتِي جَعَلْتُهَا فِي يَدِكَ وَٱصْنَعْهَا قُدَّامَ فِرْعَوْنَ. وَلَكِنِّي أُشَدِّدُ قَلْبَهُ حَتَّى لَا يُطْلِقَ ٱلشَّعْبَ.

And the LORD said unto Moses, When thou goest to return into Egypt, see that thou do all those wonders before Pharaoh, which I have put in thine hand: but I will harden his heart, that he shall not let the people go.
