1 Samuel 13:21

The charge was a pim for sharpening a plowshare or mattock, a third of a shekel for sharpening a pitchfork or an axe, and a third of a shekel for repointing an oxgoad.

1. a A pim possibly refers to a polished stone weighing approximately 0.25 ounces or 7 grams found in excavations. This is equivalent to about two-thirds of a shekel and likely refers to the price charged by the Philistines for the services listed.
2. b Hebrew does not include the currency unit of a shekel charged for sharpening a pitchfork, an axe, or an oxgoad; alternatively, possibly a third of a pim for each.
