'Closed' in the Bible

but their minds were closed. For to this day, at the reading of the old covenant, the same veil remains; it is not lifted, because it is set aside only in Christ.

He threw him into the abyss, closed it, and put a seal on it so that he would no longer deceive the nations until the 1,000 years were completed. After that, he must be released for a short time.
