On the south side ... the standard of the camp of Reuben. The description given of the position of Reuben and his attendant tribes on the south, of Ephraim and his associates on the west, of Dan and his confederates on the north, with that of Judah on the east, suggests the idea of a square or quadrangle, which, allowing one square cubit to each soldier while remaining close in the ranks, has been computed to extend over an area of somewhat more than 12 square miles. But into our calculations of the occupied space must be taken not only the fighting men, whose numbers are here given, but also the families, tents, and baggage. The tabernacle or sacred tent of their Divine King, with the camp of the Levites around it (see the note at Numbers 3:38), formed the center, as does the chief's in the encampments of all nomad people.
In marching, this order was adhered to, with some necessary variations. Judah led the way, followed, it is most probable, by Issachar and Zebulun. Reuben, Simeon, and Gad formed the second great division. They were followed by the central company, composed of the Levites, bearing the tabernacle. Then the third and posterior squadron consisted of Ephraim, Manasseh, and Benjamin; while the hindmost place was assigned to Dan, Asher, and Naphtali. Thus Judah's, which was the most numerous, formed the van; and Dan's, which was the next in force, brought up the rear; while Reuben's, and Ephraim's, with the tribes associated with them respectively, being the smallest and weakest, were placed in the center. (See the note at Numbers 10:14.)
Verse 22. Then the tribe of Benjamin. This tribe appears at this early period associated with the tribes of Ephraim and Manasseh. This was natural, considering the full consanguinity of their ancestors, Joseph and Benjamin, and this association continued in the early period of the occupation of Canaan (cf. Judges 5:14; 2 Samuel 2:9; Psalms 80:2).
Verse 23. His host, and those that were numbered of them, were thirty and five thousand and four hundred. Dr. Colenso ridicules this statement by saying that the offspring of Benjamin's ten sons was not equal to that of Dan's single son. But we have only to suppose this-that some of Benjamin's sons had no families, that their children died young, or that there was a preponderance of daughters in the one line over that in the other, to account in a very natural way for the result.
Verse 26. And his (Dan's) host, and those that were numbered of them, were threescore and two thousand and seven hundred. Dr. Colenso considers this a fictitious number, on the ground that Dan at the emigration into Egypt had only one son, Hushim (Genesis 46:23), or Shusham (Numbers 26:42). But it is quite evident that in these chapters none are mentioned but heads of families; and consequently, supposing that Dan may have had sons born to him in Egypt, they would all be reckoned as included in the family of Hushim. Even on the hypothesis that Hushim was the only son of Dan, it does not follow that there is anything incredible in the numerical increase of his tribe at the date of the census. Dr. Colenso, indeed, who supposes Hushim to have had three sons, each of these to have had three sons, and each of these grandsons to have had three sons also, makes out in the fourth generation only 27 warriors descended from him, instead of 62,700. But this is altogether a gratuitous assumption; and assuming the undoubted existence of polygamy among the Hebrews, as well as considering the immense number of sons whom some fathers in those ages had (cf. Judges 8:30; Judges 10:3-4; Judges 12:8-9; Judges 12:14; 2 Kings 10:1), we are quite prepared to receive this record of the vast increase of Dan's tribe as neither an exaggerated nor unnatural account.
