Hebrew · Strong's H3581

כֹּחַ

(KO-akh)

noun, masculine

This term refers to strength, power, or ability, encompassing physical vigor, military might, and the capacity to act.

The Hebrew word כֹּחַ (koach) denotes strength, power, or vigor in a wide range of contexts. Its semantic breadth includes physical strength, as seen in descriptions of humans, animals, or even the land's productivity. It can also refer to military might or the power of a nation. Beyond physical manifestations, koach extends to the inherent ability or capacity to perform tasks or withstand challenges. It can describe human capability as well as God's omnipotent power. The term carries theological weight, often highlighting the contrast between human weakness and God's incomparable strength. The concept of koach is frequently employed to emphasize God's redemptive acts, where His mighty power is displayed in delivering His people. It also appears in contexts of warning, where reliance on human strength is shown to be futile without divine assistance, while God's koach is always sufficient.

The word can be used both positively and negatively. Positively, it denotes desirable qualities such as physical prowess or moral fortitude. Negatively, it can describe destructive force or the oppressive power of wicked individuals or nations. In some instances, it describes the "fruits" or "produce" of the land, implying the power of the land to yield sustenance. The broad usage consistently points to some form of inherent or applied energy, capacity, or might. Understanding this range helps illuminate various biblical passages that speak of human endeavor, divine intervention, and the nature of the created world. The use of koach often serves to glorify God, reminding the reader that ultimate power and strength reside in Him.
