Numbers 32:11

Surely none of the men that came up out of Egypt, from twenty
years old and upwards
See ( Numbers 14:28 Numbers 14:29 ) .

shall see the land which I sware unto Abraham, unto Isaac, and unto
Jacob;
the land of Canaan, which at various times he sware to give to them, and to their posterity:

because they have not wholly followed me;
the laws which he prescribed them, the directions he gave them, and particularly the orders they had to go up and possess the land at once, ( Deuteronomy 1:21 ) .
