Grinding stone
Grinding stone In antiquity, it was the daily chore of women to grind the wheat and bake the bread. The lower grinding stone was mostly a large basalt stone with a rough surface. Since an adult consumed about 600 g grain per day, more then 2 kg flour had to be produced for a four or five person household. Exod 11:5 ; Judg 9:53 ; Isa 47:2 ; Job 41:24 ; Matt 24:41
