The meaning of Flour in the Bible
(From Easton's Bible Dictionary)

Grain reduced to the form of meal is spoken of in the time of Abraham (Genesis 18:6). As baking was a daily necessity, grain was also ground daily at the mills (Jeremiah 25:10). The flour mingled with water was kneaded in kneading-troughs, and sometimes leaven (Exodus 12:34) was added and sometimes omitted (Genesis 19:3). The dough was then formed into thin cakes nine or ten inches in diameter and baked in the oven.
