Numbers 14:16

It is because the Lord was not able to bring this people into the land that he swore to give to them that he has killed them in the wilderness .

‘The Lord was not able to bring these people into the land he promised them on oath, so he slaughtered them in the wilderness.`

Because the Lord was not able to bring this people into the land which he sware unto them, therefore he hath slain them in the wilderness.
