Deuteronomy 1:7-8

To the mount of the Amorites That is, to the mountainous country on the south part of Canaan, inhabited chiefly by the Amorites, Deuteronomy 1:19; Deuteronomy 1:44. The country to which Moses directed the spies to go up, Numbers 13:17. This order is not mentioned in the book of Numbers, nor a great many other things, for a knowledge of which we are indebted to this supplemental book of Deuteronomy. Behold, I have set the land before you Hebrew, before your faces; it is open to your view, and to your possession; there is no impediment in your way. And thus is the heavenly Canaan, and the kingdom of grace which leads to it, laid open to the view and enjoyment of all believers. Which the Lord sware unto your fathers, Genesis 15:18; Genesis 17:7; Genesis 28:13. It is not indeed said in any of these places that God confirmed his promise with an oath; but he did what was equivalent thereto; he engaged his veracity by the solemn transaction of a covenant, which is called the oath of God, Genesis 26:3.
