The Pharisees and Sadducees [i.e., these were strict sects of the Jewish religion], came out and began disputing with Jesus, asking for a [supernatural] sign from Him, [in an attempt] to test Him.

Then He sighed deeply in His spirit and said, "Why does this generation of people look for a [supernatural] sign? Truly I tell you, there will not be any [supernatural] sign given to this generation."

"Tell us, when will these things [you just spoke of] happen? And what will be the sign [that indicates] when all these things are about to be fulfilled?"
