'Twinkling of an Eye' in the Bible

Then he led Jesus up [to a high mountain] and displayed before Him all the kingdoms of the inhabited earth [and their magnificence] in the twinkling of an eye.

in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call. For a trumpet will sound, and the dead [who believed in Christ] will be raised imperishable, and we will be [completely] changed [wondrously transformed].
