A.T. Robertson Commentary Luke 10:24

"for I say unto you, that many prophets and kings desired to see the things which ye see, and saw them not; and to hear the things which ye hear, and heard them not." — Luke 10:24 (ASV)

Which ye see (α υμεις βλεπετε). The expression of υμεις makes "ye" very emphatic in contrast with the prophets and kings of former days.
