The Apostle Paul

Verse 20. Where is the wise? Language similar to this occurs in , "Where is the scribe? where is the receiver? where is he that counted the towers?" Without designing to quote these words as having an original reference to the subject now under consideration, Paul uses them as any man does language where he finds words with which he or his readers are familiar, that will convey his meaning.
