Deuteronomy 1:19-21

19And when we departed from Horeb, we went through all that great and terrible wilderness, which ye saw by the way of the mountain of the Amorites, as the LORD our God commanded us; and we came to Kadeshbarnea. 20And I said to you, Ye have come to the mountain of the Amorites, which the LORD our God doth give to us. 21Behold, the LORD thy God hath set the land before thee: go up and possess it, as the LORD God of thy fathers hath said to thee; fear not, neither be discouraged.
