Matthew Poole and continuators on Deuteronomy 33:12

12 And of Benjamin he said, The beloved of the LORD shall dwell in safety by him , and the LORD shall cover him all the day long , and he shall dwell between his shoulders .

(i. e.) This beloved Tribe, so called partly in allusion to their Father Benjamin who was the beloved of his Father Iacob: and partly because of the love and kindness of God towards this Tribe appeared both in this, that they dwelt in the fattest and best part of the Land, as Iosephus affirms, and especially in the following priviledge.

(i. e. Shall have his lot nigh unto Gods Temple, which was both a singular comfort and safeguard to him.

Who may well be understood here because he was expressed in the former member.

Shall protect that Tribe continually while they cleave to him.

The Lord shall dwell, i. e. his Temple shall be placed, between his shoulders, i. e. in his portion, or between his borders, or sides as the word Shoulder is oft used, as Exod. 28. 7. Numb. 34. 11. Ios. 15. 8, 10. Ezek. 47. 1, 2. And this was truly the scituation of the Temple, on both sides whereof was Benjamins portion, and though mount Sion was in the Tribe of Iudah, yet mount Moriah, on which the Temple was built, was in the Tribe of Benjamin.
