John Wesley on Luke 10:30

From Jerusalem to Jericho - The road from Jerusalem to Jericho (about eighteen miles from it) lay through desert and rocky places: so many robberies and murders were committed therein, that it was called the bloody way. Jericho was situated in the valley: hence the phrase of going down to it. About twelve thousand priests and Levites dwelt there, who all attended the service of the temple.
