Acts 24:9

And the Jews also assented, saying that these things were so.

At Caesarea the Jews who came with Tertullus joined his accusations against Paul and assented that they were true, openly backing the effort to have him condemned. Their assent added their voice to the charges laid before the Roman court in the push for a verdict against him.

It was not only the cry of a mob but the formal charge of the most honorable personages of Jerusalem headed by the high priest, joined with popular clamor for his death. They were driven by hatred, even malignant hatred, and by a desire and fixed determination to secure his condemnation and take his life rather than by love of truth. His long imprisonment had not softened nor shaken that determination.

They joined in the charges although they could not prove his guilt. Their assent reflected a hostility that led Jewish tribunals to condemn him, while Roman officials recognized his innocence.
