What Was Moses Asking for When He Said "Show me Your Glory"?

What was Moses asking for when he said to the Lord, “Show me your glory” (Exodus 33:18)?

The glory of God is the worthiness of God–the presence of God in the fullness of his attributes in some place or everywhere (Exodus 16:10; 29:43; 33:19-34:8; Isaiah 6:3). Thus, Moses wanted to see the character of God. In a sense, Moses' prayer was answered on the Mount of Transfiguration (Luke 9:30-32), where he shared a vision, however brief, of the Lord's glory with Elijah and three of Jesus' disciples.
