Pesach

Midrash Rabba (20,6) on Shemos 13,17-Pharaoh was upset that the Jews are leaving because before he was getting messages from Hashem and now he won't anymore. It's a mashal to a man who's son was far away and a rich man accepted him graciously. Then the king kept sending him messages to send his son, and then when his son finally left the rich man starting crying. People asked him why he's crying, and he said before I used to get honor because the king used to keep sending him messages and now that the son left he won't be getting them anymore. How was it a kavod to Pharaoh that Hashem kept sending him messages that if you don't send my son, I'm going to smash you to smithereens? That's not an honor, he's insulting him! It's only in honor if it was a normal message!
