So all the arguments before were just about freeing the people and not about why they should be freed?
As Allah gave Moses revelation before they left Egypt, this did not need to be written down until after the people were free, hence the mount Sinai episode. This makes much more sense than Moses only told pharaoh to let his people go. Was the Quran fully completed on day 1 of the Messenger receiving wahi or over 23 years?
You would have us believe Allah did not tell Moses that people are all equal, all worthy of dignity, etc, pharaoh did not need 'educating' but punishing?
All of the following came later?:
53:37 And (the Scrolls) of Abraham who fulfilled his obligations.
[The Divine message has essentially been the same. Herein are mentioned some of those laws, Twelve Maxims of intense beauty from the Scrolls of Abraham]
53:38 i No laden one shall bear the load of another. [6:164, 39:7, 65:7]
53:39 ii Every human being shall be responsible for his own works and compensated for his labor.
53:40 iii And soon, his effort (and not the results) will be seen.
53:41 iv Then he will be fully rewarded for it.
53:42 v To your Lord is the final destination. [79:44. Your goal shall be your Lord’s Rule on earth]
53:43 vi He is the One Who causes you to laugh, and to cry. [The basic principles that cause nations to live in prosperity versus misery, are being mentioned here]
53:44 vii He is the One Who gives death and gives life. [The rise and fall of nations follow His laws. And these laws are most excellently expounded in the Qur’an]
53:45 viii He is the One Who creates the two companions, the male and the female (pairs and opposites among His creation),
53:46 From gametes that unite.
53:47 ix He has promised to bring about a second life (the ultimate accountability).
53:48 x He is the One Who gives wealth and contentment (according to His laws).
53:49 xi He is the One Who is the Lord of the brightest star, the human intellect.
[Shi'ra = Sha'oor = Intellect. Shi'ra is also the Arabic name of the brightest star Sirius in the constellation Canis Major. It was widely worshiped in ancient Middle East]
53:50 xii He is the One Who annihilated the former tribe of ‘Aad. [They were men of intellect but refused to establish the Divine System. God never changes His laws, therefore, a wrong system, however smartly run, is bound to collapse]
