TSK · Numbers 13:25

So he was there with the LORD forty days and forty nights; he did not eat bread, and he did not drink water. He wrote on the tablets the words of the covenant, the ten commandments.

According to the number of the days you have investigated this land, forty days– one day for a year– you will suffer for your iniquities, forty years, and you will know what it means to thwart me.
