# But their minds were hardened

"But the Israelites could not understand what they saw" 

# For to this day

to the time at which Paul was writing to the Corinthians

# when they read the old covenant, that same veil remains

Just as the Israelites could not see the glory on Moses's face because he covered his face with a veil, there is a spiritual veil that prevents people from understanding when they read the old covenant. 

# when they read the old covenant

"when they hear someone read the old covenant"

# It has not been removed, because only in Christ is it taken away

"No one removes the veil, because only in Christ does God remove it"
