Acts 9:1-2

Now Saul, still breathing threats and murder against the disciples of the Lord [and relentless in his search for believers], went to the high priest, and he asked for letters [of authority] from him to the synagogues at Damascus, so that if he found any men or women there belonging to the Way [believers, followers of Jesus the Messiah], men and women alike, he could arrest them and bring them bound [with chains] to Jerusalem.
