Adam Clarke Bible Commentary

If a stranger sojourn - See the notes on Lev 19:33;Lev 22:9. When the case of the Jewish people is fairly considered, and their situation with respect to the surrounding idolatrous nations, we shall see the absolute necessity of having but one form of worship in the land. That alone was genuine which was prescribed by the Almighty, and no others could be tolerated, because they were idolatrous. All strangers - all that came to sojourn in the land, were required to conform to it; and it was right that those who did conform to it should have equal rights and privileges with the Hebrews themselves, which we find was the case. But under the Christian dispensation, as no particular form of worship is prescribed, the types and ceremonies of the Mosaic institution being all fulfilled, unlimited toleration should be allowed; and while the sacred writings are made the basis of the worship offered to God, every man should be allowed to worship according to his own conscience, for in this respect every one is "Lord of himself, accountable to none But to his conscience and his God alone."
