He heard the sound of the trumpet,.... The alarm of the enemy being at hand, and so was inexcusable:
and took not warning; which that gave him:
his blood shall be upon him; the fault shall be imputed to himself, and not another; and he must bear it himself, and answer for it, and not the watchman:
but he that taketh warning shall deliver his soul; who, hearing the sound of the trumpet, prepares for his own defence, and provides for his safety, he shall save his life, and not fall into the enemies' hands.
