And they lay wait for their [own] blood
While they lie in wait for the blood of others, they lie in wait for their own; and when they shed the blood of innocent persons, it in the issue comes upon their own heads, and is the cause of their own blood being shed; vengeance pursues them, and justice will not suffer them to live; they lurk privily for their [own] lives:
while they are lurking in secret places to take away, the lives of others, they are laying snares for their own souls; and the consequence of it will be, that they will be brought to a shameful and untimely end here, or, however, to everlasting ruin and destruction hereafter.
