Lucas 10:31

Jesus described the priest as happening to take the journey that brought him into contact with the unfortunate victim. This fact in no way excused the priest’s failure to show love, but it may suggest that from the priest’s viewpoint his discovery was accidental. Jesus simply recorded the priest’s unloving act without complicating the story with his motivation. For whatever reason, and the reason is unimportant, the priest failed to act in love even though common courtesy demanded that he stop and render aid. However a priest, of all people, should have shown compassion. He served in a "helping occupation," and he had frequent contact with the Scriptures and their demands. Moreover this priest had recently been in Jerusalem, the center of worship and spiritual influence.
