Deuteronomy 8:7-20 -

The land on which they were about to enter is described as a good laud, fertile and well watered, and yielding abundant produce to its cultivators; and they are cautioned against forgetting, in their enjoyment of the gift, the bounty of the Giver, or congratulating themselves on having achieved the conquest of such a land, instead of gratefully acknowledging the grace which had sustained them during their protracted wandering in the wilderness, and by which alone they had been enabled to take possession of that favored land.
