kab.bir describes conspicuous strength or magnitude, of persons, forces, and substantial wealth or crowds.

The attested use most often marks persons or agents as notably strong, including God and those called mighty. It also describes the force of waters and wind, and it can qualify wealth or a multitude as great in scale.

1. Powerful persons and agents · dominant

   Singular and plural masculine absolute forms describe figures characterized by strength: in Job 15:10 the APB renders older men as “mightier than your father,” while Job 34:24 says that God shatters “the mighty.” In Job 36:5, two singular forms occur in the assertions that God is mighty and that strength of heart is mighty.

   Isaiah 28:2Job 15:10Job 34:17Job 34:24Job 36:5
2. Forceful natural movement · occasional

   The plural form qualifies waters in Isaiah 17:12, where the APB renders peoples' roar as the crash of “mighty waters.” In Job 8:2, the singular form occurs with the wind-like force attributed to the words of the speaker's lips.

   Isaiah 17:12Job 8:2
3. Greatness in amount or scale · occasional

   In Job 31:25, the singular form occurs in the clause about wealth being great and the hand finding much. In Isaiah 16:14, it occurs in the prediction that Moab's remnant will be very small and “not mighty,” contrasting what remains with substantial strength or scale.

   Isaiah 16:14Job 31:25

In the Anselm Project Bible: The APB variously presents the clause with “mighty,” “mightier,” “great,” and “not mighty,” while also using “strong” in Isaiah 28:2. These are verse-level presentations rather than fixed translations of the term.
