Yechezkel 4:9

Take thou also unto thee chittin (wheat), and se'orim (barley), and fol (beans), and adosim (lentils), and dochan (millet), and kussemim (spelt), and put them in keli echad, and make thee lechem thereof, according to the mispar of the yamim that thou shalt lie upon thy side, three hundred and ninety days shalt thou eat thereof.
