In the vision, the man runs through the desert, feet still bound and hands still shackled.
The teacher sends one of his disciples to find the man and bring him to the teacher for help, healing, and support.
With instructions not to speak to the man, the disciple sets out to find him. Less than two hours later, he arrives at the cave where the teacher had seen the man in his vision. The slave huddles inside, trembling.
Remembering that he has been commanded not to speak, the disciple tries to communicate that he has come to help the slave. It doesn’t work. Probably because the slave is terrified, still tied up, and hiding in a cave.
The slave tries to run and trips. The disciple is ‘forced to subdue’ him. I imagine that the slave is slung over the back of a horse like a very scared bag of grain.
