'Letting' in the Bible

A third of you will come to death from disease, wasting away among you through need of food; a third will be put to the sword round about you; and a third I will send away to every wind, letting loose a sword after them.

Now while they were doing so, and I was untouched, I went down on my face, and crying out, I said, Ah, Lord! will you give all the rest of Israel to destruction in letting loose your wrath on Jerusalem?

Or if I send disease into that land, letting loose my wrath on it in blood, cutting off from it man and beast:

For he put his oath on one side in letting the agreement be broken; and though he had given his hand to it, he did all these things; he will not get away safe.
