a full end: something brought all the way to its finish, most often the complete destruction of a people or place.
This word names the point where something is carried all the way through to its finish. In the great majority of its appearances that finish is destruction: a nation, city, or land brought to a complete end and wiped out entirely. Its most common form is a fixed phrase, "to make a full end," which the prophets use again and again for total ruin.
Because the core idea is completeness, the same word can also work as a plain measure of degree. In a couple of places it simply means "altogether" or "to the full," describing an action done completely rather than a nation destroyed. Both uses share one thing: something taken all the way, with nothing left over.
A striking pattern runs through the judgment oracles. Again and again God declares that he will not make a full end. Even as he threatens ruin, he draws a line short of total annihilation for his own people, so the word often marks the limit of judgment rather than its full reach.
It is the noun paired with the ordinary verb (כָּלָה) meaning "to be finished" or "to be used up." Where that verb describes the action of coming to an end, this word names the end itself: the finished, exhausted result.
