An uncommon word, one Jesus only uses twice, is translated here as "highways" in KJV and "corners," in NIV version. It actually means "outlets," meaning where the main highway feeds the local roads. This indicates that the common word translated as "street" in NIV and untranslated in KJV means more of a highway than just a road.
The "as many as" here--in the KJV, left out of the NIV--is the object of the verb "find" but it is placed before the beginning of a "when" clause in which the verb appears but that clause is invisible because it is not translated in either the KJV or NIV or any other common translation. This makes the statement seem interrupted, where Jesus started to say one thing, but they said another.
