‏ Leviticus 27:16

16But if he has vowed a field of his possession, and has consecrated it to the Lord, the price shall be estimated according to the measure of the seed. If the land would be sown with thirty measures of barley, then let it be sold for fifty shekels of silver.
27:16The Hebrew unit of dry measure here is called a ‘measure’ and is equivalent to about 2 U.S. gallons.(Conte)
