tar.mit denotes deceptive conduct or speech, especially ascribed to hearts, prophets, or a tongue.

   In Jeremiah 14:14 and Jeremiah 23:26, the construct form occurs in clauses about prophets whose messages arise from deception in their own hearts; the APB renders the surrounding statements with “the deceit of their own hearts” and “the deceitfulness of their heart.” In Jeremiah 8:5 the absolute form is what Jerusalem holds fast to, while Psalm 119:118 links the construct form with those who wander from statutes; Zephaniah 3:13 places the absolute form in a clause denying that such a tongue will be found among the remnant.

In the Anselm Project Bible: The APB presents the surrounding clauses with “deceit,” “deceitfulness,” and “deceitful,” particularly in references to hearts, what Jerusalem holds fast to, and a tongue. These variations should not be treated as separate lexical senses.
