2 Corinthians 3:12-14

12Therefore, since we have such a hope, we are very bold. 13We are not like Moses, who would put a veil over his face to prevent the Israelites from seeing the end of what was passing away. 14But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away.
