ru.ach describes smelling odors, including aromas, and in several clauses frames perception in relation to fire, battle, or fear.

The attested use most often concerns smelling odors or the absence of that capacity, especially aromas associated with garments, offerings, assemblies, and idols. A smaller group uses smell-language in clauses about fire, battle, and fear of the LORD; one offering clause is rendered by the APB as acceptance rather than as smelling.

1. Smelling aromas or lacking smell · dominant

   In Genesis 27:27 the sequential imperfect occurs when Isaac smells Jacob's garments, while in Genesis 8:21 it occurs with the pleasing aroma. The imperfect forms in Amos 5:21 and Leviticus 26:31 occur in declarations that the speaker will not smell assemblies or a soothing aroma; Deuteronomy 4:28 and Psalm 115:6 likewise place the form in clauses denying smell to handmade gods.

2. Smell-language for perceived circumstances · occasional

   In Job 39:25 the imperfect describes smelling battle from afar, alongside the thunder of rulers and a shout. The infinitive constructs in Judges 16:9 and Isaiah 11:3 occur respectively in the APB's clauses about tow smelling fire and smelling in the fear of the LORD.

3. In an offering-related appeal · rare

   In 1 Samuel 26:19 the Hiphil imperfect appears in a conditional appeal concerning the LORD and an offering. The APB renders the clause "may he accept an offering," so the term's specific contribution cannot be isolated beyond its placement in that offering clause.

   1 Samuel 26:19

In the Anselm Project Bible: Across the occurrences, the APB repeatedly uses "smell" or "smelled," including aromas, garments, fire, battle, and fear. In 1 Samuel 26:19 it instead renders the offering clause "may he accept an offering"; That rendering does not by itself establish a separate lexical meaning.
