'In an Instant' in the Bible

And the multitude of thine enemies shall be like small dust, and the multitude of the terrible ones as chaff that passeth away; and it shall be in an instant, suddenly.

therefore this iniquity shall be to you as a breach ready to fall, swelling out in a towering wall, whose breaking shall come suddenly in an instant.

in an instant, in the twinkling of an eye, at the last trumpet; for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
