LUK 11:52

52 Woe to you, wise men of the law, for ye have taken away the key of cunning (or the key of knowing); and ye yourselves entered not [[in]], and ye have forbidden them that entered. (Woe to you, men wise in the Law, for ye have taken away the key of knowledge; and ye yourselves did not enter in, and ye have forbidden those who tried to enter in.)
