'Proofs' in the Bible

who came to Jesus at night and said to Him, “Rabbi (Teacher), we know [without any doubt] that You have come from God as a teacher; for no one can do these signs [these wonders, these attesting miracles] that You do unless God is with him.”

But many from the crowd believed in Him. And they kept saying, “When the Christ comes, will He do more signs and exhibit more proofs than this Man?”
