Musar su Esodo 12:46

The commandment in 12,46: "You must not break a bone of it," applies only to the owners. Dogs are allowed to break the bones of the remains. The Egyptians would come and collect the bones and inter them so that the dogs would be unable to get at them which would constitute the utter destruction of the idol. According to Halachah a Jew cannot totally destroy the deity of a Gentile; in order to be fully effective this must be done by the Gentile himself. This is why the Egyptians had to bury these bones. Causing the Egyptians to perform this act of annihilating the remains of their one time supreme deity was the most effective act of boosting the belief in the One and Only G–d of the Jews. All of the foregoing is spelled out in the Zohar.
