na.chash denotes divining or interpreting an omen, whether practiced, claimed, or prohibited in Scripture.

The attested use consistently concerns divining: a person claims to discern information, interprets an omen, or engages in a practice prohibited alongside other acts. The same use appears in personal claims of knowledge, in a claim connected with a drinking vessel, and in prohibitions or condemnatory descriptions of the practice.

   Piel forms describe a claimed means of knowing or interpreting signs: in Genesis 30:27 the APB renders Laban's claim, "I have divined that the LORD has blessed me because of you," and in 1 Kings 20:33 the men treat a spoken word as an omen. In Genesis 44:5, the supplied morphology labels the form(s) infinitive absolute in Joseph's claim concerning the vessel; the APB renders the clause, "by which he surely divines." Piel forms in Deuteronomy 18:10 and Leviticus 19:26 occur in prohibitions, while 2 Chronicles 33:6 describes the practice among actions called bad in the verse.

In the Anselm Project Bible: Across the verses, the APB uses "divined," "divines," and "practices divination," and in 1 Kings 20:33 presents the surrounding action as taking something "as an omen." It also places "soothsaying" and "observes omens" in nearby clauses, so those renderings cannot be assigned to this term with precision.
