par.osh denotes a flea, used in a comparison for a person being sought.

The supplied occurrences show the term used as a singular noun for a flea in a comparison that portrays the pursued person as a single, small target; the APB makes this explicit in 1 Samuel 26:20, while its contribution is not apparent in the translation of 1 Samuel 24:15.

   Both occurrences use the noun in the masculine singular absolute form. In 1 Samuel 26:20, the APB renders the clause "the king of Israel has come out to seek a single flea," followed by a comparison with hunting a partridge; in 1 Samuel 24:15, the APB instead renders an appeal for judgment and deliverance, so the term's specific contribution is not isolated there.

In the Anselm Project Bible: The APB explicitly includes "a single flea" in 1 Samuel 26:20. In 1 Samuel 24:15, its translation does not visibly reflect the term, so the translation is not sufficient to identify a corresponding English word there.
