Numbers 11:18-19

And say to the people, ‘Consecrate yourselves for tomorrow, and you shall eat meat, for you have wailed in the hearing of the LORD, saying, “If only we had meat to eat! Surely it was better for us in Egypt.” Therefore the LORD will give you meat, and you shall eat. You shall eat not only one day, or two days, or five days, or ten days, or twenty days
