Ulangan 2:14-15

2:14 Now the length of time it took for us to go from Kadesh Barnea to the crossing of Wadi Zered was thirty-eight years, time for all the military men of that generation to die, just as the Lord had vowed to them. 2:15 Indeed, it was the very hand of the Lord that eliminated them from within ¹  the camp until they were all gone.

[2:15]  ¹ tn Heb “from the middle of.” Although many recent English versions leave this expression untranslated, the point seems to be that these soldiers did not die in battle but “within the camp.”
