The New John Gill Exposition of the Entire BibleMark 11:33
And they answered and said unto Jesus…
by this dilemma to the greatest streight and difficulty;
we cannot tell:
they could, if they would, but they did not care to
tell; they knew if they did, they should expose themselves one way
and Jesus answering, saith unto them, neither do I tell you by what
authority I do these things; (See Gill on 21:27).
