Numbers 11:17-21

And I will come down and talk with thee there: and I will take of the spirit which is upon thee, and will put it upon them; and they shall bear the burden of the people with thee, that thou bear it not thyself alone.

And say thou unto the people, Sanctify yourselves against to morrow, and ye shall eat flesh: for ye have wept in the ears of the LORD, saying, Who shall give us flesh to eat? for it was well with us in Egypt: therefore the LORD will give you flesh, and ye shall eat.

Ye shall not eat one day, nor two days, nor five days, neither ten days, nor twenty days;

But even a whole month, until it come out at your nostrils, and it be loathsome unto you: because that ye have despised the LORD which is among you, and have wept before him, saying, Why came we forth out of Egypt?

And Moses said, The people, among whom I am, are six hundred thousand footmen; and thou hast said, I will give them flesh, that they may eat a whole month.
