14 Thirty-eight years passed from the time we left Kadesh Barnea until we crossed the Zered Valley. By then, that entire generation of fighting men had perished from the camp, as the Lord had sworn to them.
14 And the time from our leaving Kadesh-barnea until we crossed the brook Zered was thirty-eight years, until the entire generation, that is, the men of war, had perished from the camp, as the Lord had sworn to them.
14 It took us thirty-eight years to get from Kadesh Barnea to the Brook Zered. That's how long it took for the entire generation of soldiers from the camp to die off, as God had sworn they would.
14 And the time we took to come from Kadesh Barnea until we crossed over the Valley of the Zered was thirty-eight years, until all the generation of the men of war was consumed from the midst of the camp, just as the Lord had sworn to them.
14 "Thirty-eight years passed from the time we first left Kadesh-barnea until we finally crossed the Zered Brook! By then, all the men old enough to fight in battle had died in the wilderness, as the Lord had vowed would happen.
Matthew Henry's Commentary on Deuteronomy 2:14
Commentary on Deuteronomy 2:8-23
(Read Deuteronomy 2:8-23)
We have the origin of the Moabites, Edomites, and Ammonites. Moses also gives an instance older than any of these; the Caphtorims drove the Avims out of their country. These revolutions show what uncertain things wordly possessions are. It was so of old, and ever will be so. Families decline, and from them estates are transferred to families that increase; so little continuance is there in these things. This is recorded to encourage the children of Israel. If the providence of God has done this for Moabites and Ammonites, much more would his promise do it for Israel, his peculiar people. Cautions are given not to meddle with Moabites and Ammonites. Even wicked men must not be wronged. God gives and preserves outward blessings to wicked men; these are not the best things, he has better in store for his own children.
