Satan refused to prostrate

In Surah Alhijir, we see the story of Satan and how he refused to bow to Adam, the first human God created. Three verses struck me in this story. Look at the following carefully which come repeatedly throughout this story:

Verse 26:
وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
And indeed, We created man from sounding clay of altered black smooth mud.

Verse 28:
وَإِذْ قَالَ رَبُّكَ لِلْمَلَائِكَةِ إِنِّي خَالِقٌ بَشَرًا مِّن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
And (remember) when your Lord said to the angels: "I am going to create a man (Adam) from sounding clay of altered black smooth mud.

Verse 33:
قَالَ لَمْ أَكُن لِّأَسْجُدَ لِبَشَرٍ خَلَقْتَهُ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
[Iblis (Satan)] said: "I am not the one to prostrate myself to a human being, whom You created from sounding clay of altered black smooth mud."

Read the verses and the whole dialogue between God and satan. What I found most interesting was the fact that these 3 verses all emphasize one thing: the component of which man was created from. God is emphasizing this component 3 different times in this Surah and within just a few verses apart. Why is that do you think?

First of all, it could be emphasizing the insignificance of mankind. How they are literally created from nothing, merely clay or mud. That teaches us to be humble and not so arrogant. We are so small and yet our egos can get so big. When God keeps repeating the component we ourselves were created from, that should humble us down a bit.

Secondly, the repeated component could be showing how arrogantly blind Satan was. All that was preventing him to obey God and prostrate was the simple fact that the human was created from clay and mud. That's it. Nothing else. He even says it himself in the story. It shows you his stubbornness and inability to look past that fact. The component man was crated from is what ultimately built Satan's ego and made him disobey God, leading to his eternal damnation. Doesn't that sound childish? It does. And the fact that the component man was created from was repeated 3 times can prove that. Subhanallah.
