(13) And he made them wander in the wilderness forty years.--Moses here declares the fulfilment of the prediction which he had announced in obedience to the Divine commandment at the time when the spies brought up an evil report of the land. (See Numbers 14:33-34.)

32:6-15 The proposal showed disregard to the land of Canaan, distrust of the Lord's promise, and unwillingness to encounter the difficulties and dangers of conquering and driving out the inhabitants of that land. Moses is wroth with them. It will becomes any of God's Israel to sit down unconcerned about the difficult and perilous concerns of their brethren, whether public or personal. He reminds them of the fatal consequences of the unbelief and faint-heartedness of their fathers, when they were, as themselves, just ready to enter Canaan. If men considered as they ought what would be the end of sin, they would be afraid of the beginning of it.And the Lord's anger was kindled against Israel,.... For murmuring against the report of the spies:

and he made them wander in the wilderness forty years; for though it was but about thirty eight years from that time that they were in the wilderness, the round number of forty is given; and besides it includes the time of their first coming into it, which being reckoned, makes the complete number, within a few months: Kadesh, from whence the spies were sent, and whither they returned, and where the people murmured, and had this sentence pronounced on them, that they should not see the land of Canaan, but wander and fall in the wilderness, seems to have had the addition of Barnea made unto it on that account, which signifies the son of him that wandereth:

until all the generation which had done evil in the sight of the Lord was consumed; as they all were at this time when Moses spake these words.
