Flour: 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. Fine flour was
offered by the poor as a sin-offering
(Leviticus 5:11-13) and also in
connection with other sacrifices
(Numbers 15:3-12; 28:7-29)
