'Weight' in the Bible

So David gave Ornan 600 shekels of gold by weight for the site.

for the golden utensils, the weight of gold and silver for all the gold and silver articles for every kind of service;

and the weight of gold for the golden lampstands and their golden lamps, with the weight of each lampstand and its lamps; and the weight of silver for the silver lampstands, with the weight of each lampstand and its lamps according to the use of each lampstand;

the gold by weight for each table of showbread, and the silver for the tables of silver;

and the forks, the basins, and the pitchers of pure gold; and for the golden bowls with the weight for each bowl; and for the silver bowls with the weight for each bowl;

and for the altar of incense refined gold by weight; and gold for the model of the chariot of the cherubim that spread their wings and covered the ark of the Lord’s covenant.
