Dimnah with her suburbs, etc. - It is well known to every Hebrew scholar that the two following verses are wholly omitted by the Masora; and are left out in some of the most correct and authentic Hebrew Bibles. Between critics there is no small controversy relative to the authenticity of these verses; and those who wish to see the arguments at large on both sides, must consult the Variae Lectiones of De Rossi on this place. Dr. Kennicott, who is a strenuous advocate for their authenticity argues thus in their behalf: "Joshua 21:41 and Joshua 21:42 of this chapter tell us that the Levitical cities were forty-eight, and that they had been all as such described; so that they must have been all specified in this chapter: whereas now in all the Hebrew copies printed in full obedience to the Masora, which excludes two verses containing four of these cities, the number amounts only to forty-four.
"The cities are first mentioned, in the general, as being thirteen and ten, with thirteen and twelve, which are certainly forty-eight. And yet when they are particularly named, Joshua 21:13-19 gives thirteen cities; Joshua 21:20-26 gives ten cities; Joshua 21:27-33 gives thirteen; Joshua 21:34-36 gives four cities; and Joshua 21:35-36 gives four more, all which can make but forty-four. And what still increases the wonder is, that Joshua 21:40 infers from the verses immediately preceding, that the cities allowed to the Merarites were twelve, though they here make eight only, unless we admit the four other cities expressed in those two verses, which have been rejected by that blind guide the Masora. In defiance of this authority these two verses, thus absolutely necessary, were inserted in the most early editions of the Hebrew text, and are found in Walton's Polyglot, as well as in our English Bible. But they have scarce ever been as yet printed completely, thus, And out of the tribe or Reuben, A City of Refuge for the Slayer, Bezer, in the Wilderness, with her suburbs, and Jahazah with her suburbs, Kedemoth with her suburbs, and Mephaath with her suburbs; four cities. See on this place my edition of the Hebrew Bible, where no less than one hundred and forty-nine copies are described, which happily preserve these verses, most clearly essential to the truth and consistency of this chapter. See also General Discourse, pp. 19, 26, 54."
Though this reasoning of Dr. Kennicott appears very conclusive, yet there are so many and important variations among the MSS. that retain, and those that reject these verses, as to render the question of their authenticity very difficult to be determined. To Dr. Kennicott's one hundred and forty-nine MSS. which have these two verses, may be added upwards of forty collated by De Rossi. Those who deny their authenticity say they have been inserted here from 1-Chronicles 6:78, 1-Chronicles 6:79, where they are found it is true, in general, but not exactly as they stand here, and in Dr. Kennicott's Hebrew Bible.

Dimnah with her suburbs,.... Nowhere mentioned, unless the same with Rimmon, 1-Chronicles 6:77,
Nahalal with her suburbs; see Joshua 19:15,
four cities; only two are mentioned, 1-Chronicles 6:77; and they by different names; the one is Rimmon, before observed, and the other Tabor; perhaps the same with Chislothtabor, Joshua 19:12.
