   Moses himself had twice given express orders for this
   solemnity; once De 11:29, 30, in which he pointed out the very
   place where it was to be performed; and again, at the 27th
   chapter, there is a renewal of the instructions to Joshua,
   with special reference to minute particulars.  It was a
   federal transaction:  the covenant was now renewed between God
   and Israel upon their taking possession of the land of
   promise, that they might be encouraged in the conquest of it,
   and might know upon what terms they held it, and come under
   fresh obligations to obedience.
