For some days he was with the disciples at Damascus. 20 And immediately he proclaimed Jesus in the synagogues, saying, “He is the Son of God.” And all who heard him were amazed and said, “Is not this the man who made havoc in Jerusalem of those who called upon this name? And has he not come here for this purpose, to bring them bound before the chief priests?” But Saul increased all the more in strength, and confounded the Jews who lived in Damascus by proving that Jesus was the Christ. When many days had passed, the Jews plotted to kill him, but their plot became known to Saul. They were watching the gates day and night in order to kill him, but his disciples took him by night and let him down through an opening in the wall, lowering him in a basket. (Acts 9:19b-22)
Saul immediately testifies to fellow Jews in Damascus that Yeshu the man is the Messiah Son foretold in their scriptures.
This enfuriates those Jews, so his new friends have to smauggle him out of the city by night.
Years later Saul remembered that this was the first of the occasions he had to suffer for Yeshu’s sake.
