Numbers 14:22, 33-34

Because all those men which have seen my glory, and my miracles, which I did in Egypt and in the wilderness, and have tempted me now these ten times, and have not hearkened to my voice

And your children shall wander in the wilderness forty years, and bear your whoredoms, until your carcases be wasted in the wilderness. After the number of the days in which ye searched the land, even forty days, each day for a year, shall ye bear your iniquities, even forty years, and ye shall know my breach of promise.
