Then the chief priests and the elders of the Peoplea were gathered together in the courtyard of the high priest, the one called Caiaphas, Bible see other translations
The nation of Israel was called “the People,” so it is appropriate to capitalize it when it refers to Israel.

“the one called Caiaphas.” The reason that Caiaphas had to be named was that Annas was also the High Priest. Annas should have been the only High Priest, since the High Priest served until death, but the Romans favored Caiaphas and made him the High Priest.
