Moses Commits Manslaughter
[28:15] Once he entered the city unexpectedly, without being recognized by the people. He found two men fighting; one was (a Hebrew) from his people, and the other was (an Egyptian) from his enemies. The one from his people called on him for help against his enemy. Moses punched him, killing him. He said, “This is the work of the devil; he is a real enemy, and a profound misleader.” [28:16] He said, “My Lord, I have wronged my soul. Please forgive me,” and He forgave him. He is the Forgiver, Most Merciful. [28:17] He said, “My Lord, in return for Your blessings upon me, I will never be a supporter of the guilty ones.” [28:18] In the morning, he was in the city, afraid and watchful. The one who sought his help yesterday, asked for his help again. Moses said to him, “You are really a troublemaker.”
Why was Moses allowed to commit manslaughter while Joseph was not allowed from falling for the seduction of the governor’s wife?
Appendix 14 – Predestination
Was it Joseph who controlled his lust? Or, was it God’s protection from sin that rendered him chaste? Such is predestination.
