Leviticus 22:10 - Joseph Benson’s Commentary on the Old and New Testaments

There shall no stranger eat of the holy thing By holy thing here is meant, that portion of the sacrifices which belonged to the priests. And by stranger is not meant one of another nation, in distinction from a native Jew, but one who was not of the priest's own family, whether Jew, or Gentile proselyte. A sojourner One that came to his house, and abode there for a season, and ate at his table, was not to eat of it. There is one exception, however, to this rule, in the next verse.
