Pim weight

Pim weights (Hebrew פִּים‎ pîm) were polished weight-stones about 15 mm (5/8 inch) diameter, equal to about two-thirds of a Hebrew shekel.

Prior to the discovery of the weights by archaeologists, scholars did not know how to translate the word פִּים (pîm) in 1 Samuel 13:21.

[1] The 1611 translation of the King James Version of the Bible rendered the verse thus: Robert Alexander Stewart Macalister's excavations at Gezer (1902-1905 and 1907-1909) were published in 1912 with an illustration showing one such weight, which Macalister compared to another published in 1907 by Charles Simon Clermont-Ganneau.

[2][3] Based on this discovery, subsequent biblical translations were improved.

The 1982 New King James Version rendered 1 Samuel 13:21:
