God considered the meal, sin, and trespass offerings "most holy"(6:17, 25; 7:1, 6). This means that they were sacrifices that only the priests could eat.
The "layman who touched these most holy things became holy through the contact, so that henceforth he had to guard against defilement in the same manner as the sanctified priests (21:1-8), though without sharing the priestly rights and prerogatives. This necessarily placed him in a position which would involve many inconveniences in connection with ordinary life."65
These instructions about the meal offering underline the priests' rights. They could eat this offering but only in a holy place, such as the tabernacle courtyard. The priests enjoyed special privileges, but they also had to observe high standards of behavior. This is also true of Christians compared to non-Christians (cf. Luke 12:48; James 3:1; 1 Pet. 4:17).
