When He had come into the Temple, the leading priests and elders of the [Jewish] people came to Him while He was teaching, and said, “By what authority are you doing these things [i.e., miracles and teaching]? And who gave you this authority?”
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.
And when the crowds thronged around Jesus, He began saying, “This generation of people is evil, [for] it is looking for a [supernatural] sign. But no [such] sign will be given to it except the sign [demonstrated in the life] of Jonah.
And this is the testimony John [the Immerser] gave when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” [Note: Levites were men who assisted the priests in the Temple service].
And they said to Him, “What kind of a [miraculous] sign will you perform so that we can see it and [then] believe [in] you? What [kind of] deed will you perform?
And when these men had Peter and John brought before them, they asked, “By whose authority or in what name have you done this thing [i.e., healed the crippled man]?”
“We strictly commanded you not to teach in this name [i.e., the name of Jesus] and look [what you have done]; you have filled Jerusalem with your teaching and you intend to hold us responsible for this man’s [i.e., Jesus'] death.”
