Luke 10:32

“And in the same way a Levite also, when he came to the place, and saw him, passed by on the other side.”

The lesson is doubly rammed home by then speaking of a Levite who did the same thing, for the same reason. Levites were cultic officials and served in the Temple as ‘servants' to the priests. They too would not want to become ‘unclean'. This is therefore a doubly-emphasised witness to the failure of the servants of the Temple. And the fact that Jesus included only Temple servants as illustrations suggests that He wanted to emphasise the lesson of the corruption of the Temple and those who served in it, and prevents us from seeing this as just a story with one simple point, although it is true that a large number of the officials working in the Temple did in fact live in Jericho. We should remember that in the not too distant future He will call that Temple also ‘a den of robbers' (Luke 19:46).
