Six of their names on one stone
The names of the six eldest on the stone upon the right shoulder:
and the other six names of the rest on the other
the names of the six youngest on the stone upon the left shoulder; for these stones, as afterwards said, were put on the shoulders of the priests,
according to their birth;
the order of it; so that upon the first stone were engraven the names of Reuben, Simeon, Levi, Judah, Dan, and Naphtali; and on the second stone the names of Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin; and so they are disposed by Jarchi, with whom Josephus agrees F1; though some Jewish writers, and particularly Maimonides F2, place them otherwise; but this seems most agreeable to the letter and sense of the text.
