Matthew 2:4

“And when he had gathered all the chief priests, etc.] Here we have an account of Herod’s conduct at this juncture; he calls a council, assembles the sanhedrim, gathers together the more learned persons in the city to consult with them upon this matter, the chief priests, all of which he gathered together, and which seem to be many; and were not only the then present high priest and his substitutes, but all the principal persons of the priesthood, who were chosen from the rest, into the great sanhedrim, or council: and by the scribes of the people are meant a sort of letter learned men, whose business it was to keep and write out copies of the law, and other things, for “the people”; they…”

“And when he had gathered all the chief priests and scribes of the people together--The class of the "chief priests" included the high priest for the time being, together with all who had previously filled this office; for though the then head of the Aaronic family was the only rightful high priest, the Romans removed them at pleasure, to make way for creatures of their own.

Whence the chief of them were called doctors of the law. Matthew 2:6”

“2:4 The leading priests had political and religious clout and ministered predominantly in the Temple (see 21:23). Herod gathered the teachers of religious law because they were trained to know Old Testament prophecies and were often influential Pharisees.”
