Albert Barnes Commentary Luke 10:32

"And in like manner a Levite also, when he came to the place, and saw him, passed by on the other side." — Luke 10:32 (ASV)

A Levite. The Levites, as well as the priests, were from the tribe of Levi and were set apart for the duties of religion. The specific duty of the priest was to offer sacrifice at the temple; to present incense; and to conduct the morning and evening services of the temple, etc.

The office or duty of the Levites was to provide assistance to the priests in their services. During the journey of the Israelites through the wilderness, it was their duty to transport the various parts of the tabernacle and the sacred utensils.

It was also their duty to ensure that the tabernacle and the temple were kept clean and to prepare supplies for the sanctuary, such as oil, incense, wine, etc. Furthermore, they had the care of the sacred revenues, and after the time of David, they conducted the sacred music of the temple service (Numbers 8:5–22; 1 Chronicles 23:3–5, 23:24-32; 1 Chronicles 24:27–31).

Came and looked on him. Critics note here that the expression used does not indicate, as in the case of the priest, that he accidentally saw him and took no further notice of him, but that he came and looked on him more attentively, but still did nothing to relieve him.
