la.chash denotes a charm or charm-related utterance, especially in contexts of serpents and skilled practitioners.

The attested uses chiefly concern a charm employed in relation to serpents or understood by a skilled person; a plural occurrence also places such items among adornments. Isaiah 26:16 uses the singular in a distress-setting whose specific contribution is less clear in the translation.

1. Charm used with serpents or known by a practitioner · dominant

   In Ecclesiastes 10:11 the singular occurs in the clause about a serpent biting before it is charmed, and in Jeremiah 8:17 the APB renders serpents that cannot be charmed. In Isaiah 3:3, the singular is associated with a person described as understanding charm.

2. Charm item or quiet utterance in other settings · occasional

   Isaiah 3:20 uses the plural among headdresses, bracelets, sashes, and other listed items, where the APB renders “the charms.” In Isaiah 26:16 the singular appears in a distress clause that the APB renders with “a whisper of discipline,” so the term's precise contribution there cannot be isolated from the translation.

   Isaiah 3:20Isaiah 26:16

In the Anselm Project Bible: The APB uses “charmed,” “charm,” and “charms” in the serpent, practitioner, and item-list contexts. In Isaiah 26:16 it instead renders the clause with “a whisper of discipline”; That phrase cannot securely be treated as the term's specific rendering.
