In a paper which was published in this journal several years ago I), Professor G. E. WRIGHT challenged the usual interpretation of passages in Deuteronomy referring to priests and Levites. He tells the reader that he began by accepting the usual view but that a careful study of the evidence led him to explain these passages in a different way. A theory advanced by so eminent a scholar is certainly worthy of serious consideration, especially since he believes that its implications are many and important. He does not himself state or discuss these implications, because he thinks that the correctness of his thesis must first be tested by others. The present paper offers such a testing of Dr. WRIGHT's interesting and stimulating theory.
