How did Paul escape the governor under Aretas in Damascus?

Les explains that Paul had met the Lord on the road, was stricken blind, then received food and his sight back, and proclaimed in the synagogue that Jesus was the Christ. But that was no longer sufficient, because God had further revelations for him. When word came that Jews were ready to put him to death since he had turned coat, he had to flee for his life. As Paul wrote, the governor under Aretas the king kept the city of the Damascenes with a garrison desirous to apprehend him, but through a window in a basket he was let down by the wall and escaped his hands. Les notes this was a rough way to start a career, part of preparing him to take the Gospel of Grace.
