This feminine noun denotes strength and mighty power, used particularly of God's abundant strength. Isaiah 40:29 promises that God 'gives power to the faint and increases strength to the powerless,' using this word for the vigor He supplies. Isaiah 47:9 warns Babylon that calamities will come upon her 'despite the great power of your sorceries,' her magical might proving futile. Nahum 3:9 describes Ethiopia and Egypt as Nineveh's strength, questioning 'was her strength infinite?' before detailing her fall. The word emphasizes robust, vigorous strength, the kind of power that seems abundant and unshakeable until tested.
