What does the Bible say about the veil in 2 Corinthians 3?

In 2 Corinthians 3:13, Paul discusses the veil that was over Moses' face, which represented a barrier that prevented the people from seeing the end of the Old Covenant. This veil is a metaphor for spiritual blindness that exists for those who still cling to their own righteousness under the law. Until a person turns to Christ, they remain under this veil and cannot perceive the greater glory revealed in the New Covenant, which is centered in Christ alone. The veil symbolizes their inability to recognize that the old system is abolished in Christ, preventing them from witnessing the true glory of God.
