Numbers 14:16

16 that the reason ADONAI slaughtered this people in the desert is that he wasn't able to bring them into the land which he swore to give them.

Numbers 14:16 In-Context

14 they will tell the people living in this land. They have heard that you, ADONAI, are with this people; that you, ADONAI, are seen face to face; that your cloud stands over them; that you go ahead of them in a column of cloud by day and a column of fire by night.
15 If you kill off this people at a single stroke, then the nations that have heard of your reputation will say
16 that the reason ADONAI slaughtered this people in the desert is that he wasn't able to bring them into the land which he swore to give them.
17 So now, please, let Adonai's power be as great as when you said,
18 'ADONAI is slow to anger, rich in grace, forgiving offenses and crimes; yet not exonerating the guilty, but causing the negative effects of the parents' offenses to be experienced by their children and even by the third and fourth generations.'
