'Forty Years' in the Bible

It is [only] eleven days’ journey from Horeb (Mount Sinai) by way of Mount Seir to Kadesh-barnea [on Canaan’s border; yet Israel wandered in the wilderness for forty years before crossing the border and entering Canaan, the promised land].

For the LORD thy God hath blessed thee in all the works of thy hand: he knoweth thy walking through this great wilderness: these forty years the LORD thy God hath been with thee; thou hast lacked nothing.

And thou shalt remember all the way which the LORD thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no.

Thy raiment waxed not old upon thee, neither did thy foot swell, these forty years.

And I have led you forty years in the wilderness: your clothes are not waxen old upon you, and thy shoe is not waxen old upon thy foot.
