"And I will harden Pharaoh's heart, and multiply My signs and My wonders in the land of Egypt." (Shemot 7:3).
I read the verse tonight and suddenly a question come to mind: If Hashem hardened Pharaoh's mind, does he always hardened the minds of other wicked people who are like Pharaoh?
"While the word was in the king's mouth, there fell a voice from heaven: 'O king Nebuchadnezzar, to thee it is spoken: the kingdom is departed from thee." (Daniel 4:28).
Did Hashem talk with Nebuchadnezzar at that time? Please explain.
