For the children of Israel walked forty years in the wilderness, till all the people that were men of war, which came out of Egypt, were consumed, because they obeyed not the voice of the Lord: unto whom the Lord sware that he would not shew them the land, which the Lord sware unto their fathers that he would give us, a land that floweth with milk and honey. (Joshua 5:6)
That is, with the exception of Caleb and Joshua (Num. 14:30). It seems that the priests, possibly all the Levites, were exempted from the death sentence at Kadesh and that some of them survived. Eleazar, the son of Aaron, is specifically named as entering the Promised Land (see Ex. 6:25; 28:1; Joshua 24:33). There was no representative of the Levites among the 12 spies (Num. 13:3-16), nor among the “men of war.”
