"till the Last Trump"

“Behold I show you a mystery we shall not all sleep but we shall all be changed. In a moment, in a twinkling of an eye, at the last trump, for the trumpet shall sound and the dead shall be raised incorruptible and we shall be changed. " (1 Corinthians 15:51,52).

The phrase is variously rendered as "trump" or "trumpet" in different versions of the Bible. Elliott may here be betraying his Protestant upbringing.
