Deuteronomy 2:14-15

¹⁴And the days in which we came from Kadesh-barnea, until we were come over the brook Zered, were thirty and eight years; until all the generation of the men of war were consumed from the midst of the camp, as Jehovah sware unto them. ¹⁵Moreover the hand of Jehovah was against them, to destroy them from the midst of the camp, until they were consumed.
