“My lord, listen to me. A piece of land worth 400 shekels of silvera—what is that between me and you? Bury your dead.” Bible see other translations
Roughly ten pounds (4.6 kg).

“400 shekels.” If the shekel of Abraham’s time is the same as later shekels, it was 11 or 11.5 grams, or about .4 ounces. So 400 shekels would be about 10 pounds or 4.6 kilograms. This seems to be a lot of money for the field, but we don’t know how big it was (see commentary on Gen. 24:22).
