They don't. Who are "you" in verse 9?
The book of Acts gives a complete account of how the disciples were persecuted in the very ways Jesus had predicted. Let us take, for example, Acts 4: "And they laid hands on them [Peter and John], and put them in prison" (verse 3). They were brought before "rulers" (verses 5-7). And it turned into an opportunity to testify. Peter explained that "there is none other name under heaven given among men, whereby we must be saved" (verse 12). They were given a mouth of wisdom which their adversaries could not gainsay, for the men of the council "marveled" (verse 13). They were then commanded "not to speak at all nor teach in the name of Jesus" (verse 18). As Jesus had said, they were hated for His name's sake.
The same things are seen in Acts 5. Certain authorities "laid their hands on the apostles, and put them in the common prison" (verse 18). Later they were brought "before the council" (verse 27) and told to answer for continuing to teach in the name of Jesus (verse 28). Again they had opportunity to testify (verses 29-32). They were "beaten" (verse 40). As they departed from the "council", they rejoiced "that they were counted worthy to suffer for his name"(verse 41).
Or take Acts 6. There arose certain ones of the "synagogue" that disputed with Stephen. "And they were not able to resist the wisdom and the spirit by which he spoke" (verses 9,10). Persecution resulted and he was brought into the "council " and questioned (verse 12). Again there was the opportunity to testify, the words of that testimony being given in Acts 7. Stephen was killed for his stand (verses 54-60). Jesus had said that some of them would be killed.
Notice Acts 8. "There was a great persecution against the church." Christians were put in "prison", but the result was that the word was preached (verses 1-4).
In Acts 16, Paul and Silas were beaten and cast into "prison." But it turned into an opportunity to testify and the Philippian jailor and his family were converted as a result (verses 22-34). In Acts 21, persecution resulted in Paul being beaten, brought before rulers, before whom he testified (Acts 22). In
Acts 22:19 we read that Christians were "imprisoned and beat in every Synagogue."
In Acts 24, Paul was brought before Felix, the governor, and testified. He was given a mouth of wisdom which his adversaries could not gainsay—though they obtained an orator to speak against him. Paul's words even made Felix to "tremble." In Acts 25 and 26, Paul was brought before king Agrippa, the chief captains, and the principal men of the city. He was given a mouth of wisdom, for Agrippa said to Paul, "Almost thou persuadest me to be a Christian" (verse 28).
Jesus said the disciples would be afflicted, beaten, imprisoned; they would be hated for his name's sake and some would be killed; they would be brought before councils, rulers, and kings, for a testimony; they would be given a mouth of wisdom which their adversaries could not gainsay. Surely these things came to pass in those years—unmistakably fulfilled in every detail.
