Moshe went to see how his brethren were faring and he noticed that an Egyptian was striking a Hebrew man. He killed the Egyptian and buried him in the sand. וַיִּשְׁמַע פַּרְעֹה אֶת הַדָּבָר הַזֶּה “Pharaoh heard about this matter…”. (Ex. 2,15) The Torah tells us that when Pharaoh heard this he wanted to kill Moshe and Moshe had to flee to Midian.
Jews were being beaten and killed daily. This Pharaoh did not hear. When one Egyptian was killed Pharaoh heard of it. This is the story of generations. When Jews are slaughtered all over the world no one takes heed. When a Holocaust occurs no one is concerned. When one Egyptian is killed it makes an impression.
Thousands of Jews have been killed in Israel by terrorists and no one in the world lifted their voice in protest. When Israel protects itself and kills a terrorist the world is up in arms. This started with Pharaoh and continued throughout the centuries down to our own days.
