The adhesion of Benjamin to Judah at this time comes upon us as a surprise. By blood Benjamin was far more closely connected with Ephraim than with Judah. All the traditions of Benjamin were antagonistic to Judah, and hitherto the weak tribe had been accustomed to lean constantly on its strong northern neighhour. But it would seem that, in the half-century which had elapsed since the revolt of Sheba, the son of Bichri 2 Samuel 20:1, the feelings of the Benjamites had undergone a complete change. This is best accounted for by the establishment of the religious and political capital at Jerusalem, on the border line of the two tribes Joshua 15:8; Joshua 18:16, from where it resulted that the new metropolis stood partly within the territory of either, and was in a certain sense common to both. One of the gates of Jerusalem was “the high gate of Benjamin” Jeremiah 20:2; and probably Benjamites formed a considerable part of the population. The whole tribe also, we may well believe, was sincerely attached to the temple worship, in which they could participate far more freely and more constantly than the members of remoter tribes, and to which the habits of forty years had now accustomed them.
On the number of the Israelites, see Exodus 12:37, notes; and 2 Samuel 24:9, notes. The number mentioned here is moderate, compared with the numbers given both previously and subsequently 2 Chronicles 13:3; 2 Chronicles 17:14-18.
