Adam Clarke on Numbers 14:37

Those men that did bring up the evil report died - Thus ten of the twelve that searched out the land were struck dead, by the justice of God, on the spot! Caleb, of the tribe of Judah, and Joshua, of the tribe of Ephraim, alone escaped, because they had followed God fully. Let preachers of God's word take heed how they straiten the way of salvation, or render, by unjust description, that way perplexed and difficult which God has made plain and easy.
