Numbers 14:33-35

Young's Literal Translation

³³ and your sons are evil in the wilderness forty years, and have borne your whoredoms till your carcases are consumed in the wilderness;

³⁴ by the number of the days [in] which ye spied the land, forty days, -- a day for a year, a day for a year -- ye do bear your iniquities, forty years, and ye have known my breaking off;

³⁵ I [am] Jehovah, I have spoken; if I do not this to all this evil company who are meeting against me; -- in this wilderness they are consumed, and there they die.'
