Then whosoever heareth the sound of the trumpet, and taketh no warning,.... Does not mind the notice given him; is incredulous of the danger he is in, or negligent of providing for his safety; fancies it is an alarm, and nothing else; and imagines there is no real danger, or what is a mere trifle; or, that the enemy is at a great distance, and it is time enough to provide for his defence:
if the sword come and take him away; those that kill with the sword, as the Targum, come suddenly on him, and take away his life, or carry him captive: his blood shall be upon his own head; the guilt of his slaughter, as the Targum; the sin will be his own; it must be brought in wilful murder; no blame can be laid upon any but himself; the watchman will be clear.
blood . . . upon his own head--metaphor from sacrificial victims, on the heads of which they used to lay their hands, praying that their guilt should be upon the victims.
