The key to this verse is the word translated as "reverence" which means "to be turned around." Christ commonly uses this idea of "turning around" to describe changing behavior but that idea is lost in translation. For example. the word "repent" in the phrase, "Repent, the kingdom of heaven is at hand" means to "turn around."
Missing in this verse is the little joke that appears in the version in Mark Mark 12:6. A lot happened before you came.
