When Moses asked God to "Please show me your glory," he was primarily seeking a deeper understanding of God's character and presence. In the context of the biblical narrative, this request expresses Moses' desire for a closer relationship with God and a greater revelation of God's nature. Therefore, the most accurate answer is:
Moses wanted God to reveal his exact character qualities.
This request comes from a longing to know God more intimately and to understand the essence of who God is, rather than merely wanting a display of power or spectacle.
