la.tash describes sharpening implements and weapons, with hostile imagery involving eyes and a deceitful tongue.

The attested uses chiefly concern the sharpening or preparation of implements and weapons: plowshares and farm tools in 1 Samuel 13:20, toolmaking in Genesis 4:22, and arrows in Psalm 7:13. Job 16:9 and Psalm 52:4 place the term in hostile imagery involving eyes and a deceitful tongue, though the translation does not isolate its precise contribution in the latter verse.

1. Sharpening or preparing implements · dominant

   In 1 Samuel 13:20, the Qal infinitive construct occurs where the APB renders the action as going to “sharpen” plowshares, mattocks, axes, and hoes. Genesis 4:22 uses a Qal active participle in the description of Tubal-cain, whom the APB renders as having “forged all kinds of tools of bronze and iron”; Psalm 7:13 has a Qal imperfect in the clause where the APB says that arrows are prepared.

2. Hostile figurative sharpening · common

   In Job 16:9, the Qal imperfect appears in an adversarial description, and the APB renders the clause “my adversary sharpens his eyes against me.” Psalm 52:4 has a Pual passive participle in a verse addressing a “deceitful tongue”; the APB does not make the term's individual rendering identifiable there.

   Job 16:9Psalm 52:4

In the Anselm Project Bible: The APB explicitly uses “sharpen” in 1 Samuel 13:20 and Job 16:9, while it uses “forged” in Genesis 4:22 and “prepares” in Psalm 7:13. In Psalm 52:4, the translation gives the verse's reference to a “deceitful tongue” without a clearly isolable rendering of the term.
