'Mighty' in the Bible

“Flight will be lost to the swift [so they will be unable to escape],And the strong shall not strengthen nor maintain his power,Nor shall the mighty man save his own life.

“Even the bravest among the warriors shall flee naked on that day,” says the Lord.

For I know your transgressions are many and your sins are great (shocking, innumerable),You who distress the righteous and take bribes,And turn away from the poor in the [court of the city] gate [depriving them of justice].

“But let justice run down like watersAnd righteousness like an ever-flowing stream [flowing abundantly].
