You were an anointed guardian cherub. I placed you; you were on the holy mountain of God; in the midst of the stones of fire you walked. You were blameless in your ways from the day you were created, till unrighteousness was found in you. (Ezekiel 28:14–15)
Q: What was the first sin?
A: We learn about it and Satan’s fall from Isaiah 14:12–15:
How you are fallen from heaven, O Lucifer, son of the morning!How you are cut down to the ground, You who weakened the nations! For you have said in your heart: “I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation On the farthest sides of the north; I will ascend above the heights of the clouds, I will be like the Most High.” Yet you shall be brought down to Sheol, To the lowest depths of the Pit. (NKJV)

(NKJV)
It is obvious from the text that Satan’s sin was pride."
