In Exodus 33, what did Moses ask God to show him?

Answer: Your glory

Moses said, "Please show me Your glory," and God promised to make His goodness pass before him.

“Then Moses said, “Please show me Your glory.” “I will cause all My goodness to pass before you,” the LORD replied, “and I will proclaim My name—the LORD—in your presence. I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.””— Exodus 33:18-19 (BSB)
