Numbers 11:18-20

And say thou unto the people, Sanctify yourselves against to-morrow, and ye shall eat flesh; for ye have wept in the ears of Jehovah, saying, Who shall give us flesh to eat? for it was well with us in Egypt: therefore Jehovah 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 a whole month, until it come out at your nostrils, and it be loathsome unto you; because that ye have rejected Jehovah who is among you, and have wept before him, saying, Why came we forth out of Egypt?
