And they lay wait for their own blood; they lurk privily for their own lives.
And they lay wait for their (own) blood; they lurk privily for their (own) lives. While they fancy that they are, with the certainty of success, 'laying wait for the blood' of "the innocent" (Proverbs 1:11), it proves really to be their own blood that they, with all their lying in wait, cause to be shed (Psalms 7:15-16). Compare the same retribution, "blood" for "blood," Revelation 16:6.
