For he knew that the chief priests
The Persic version reads in the singular, "the chief of the priests", or the high priest, Caiaphas,

had delivered him for envy;
at his popularity through his doctrine and miracles, and not from any principle of equity and justice, or from any regard to Caesar; (See Gill on Matthew 27:18).
