to perish, or to make something perish: to come to a final end, or to put a person or thing out of existence for good.
This is the Aramaic verb for something being gone. It runs in two directions, and which direction is meant depends on the form of the verb rather than on any change in what it means: a thing can perish on its own, or somebody can make it perish. Both are the same idea seen from either side, much as English can say a fire went out or that someone put it out.
In Daniel 2 the word is a death sentence. When Nebuchadnezzar orders that the wise men of Babylon be destroyed, the next two verses describe that same decree with the ordinary word for killing (קְטַל), so "destroy" here means execute. Daniel asks the officer in charge not to carry it out, and he and his friends pray through the night that they will not be swept away with the rest.
In Daniel 7 the target is a power rather than a person. The beast's body is destroyed and thrown into the fire, and the arrogant horn's rule is taken away to be consumed and destroyed to the very end, where our word stands next to a second verb for wiping out (שְׁמַד). Setting the two side by side is the writer's way of saying that nothing of that rule survives.
The one use outside Daniel sits in a single Aramaic verse dropped into the Hebrew of Jeremiah: the gods who did not make heaven and earth will themselves perish from the earth. Nobody is named as doing the destroying there. The idols simply stop being.
