Then they turned back from him.
They turned away from him.
But they turned their backs and went away from him
So they turned their backs on him, going away
So they turned away from him giving their backs
So they left him alone and went [to some kind of general gathering.]
And they turned their backs on him and went away. (The pagans thought he would transmit the disease)
So they went away from him, turning their backs
At that they turned their backs on him and left (for the festival)
So those people turned their backs upon him and left him
So they turned away from him, and departed (for fear of the disease)
