The term 'Biblical Dry Measure' refers to three different units of measurement used in the Bible. The first is an Ephah, which is a unit of dry measure equal to 10 omers or one-tenth of a homer. The second is a CAB, which is a unit of dry measure equal to one-sixth of an ephah. The third is an Omer, which is a unit of dry measure equal to one-tenth of a homer. All three of these units of measurement were used in the Bible to measure grain and other dry goods.
