Psalms 72:14 - Matthew Poole's English Annotations on the Holy Bible

Deceit and violence; the two ways whereby the souls or lives of men are usually destroyed. Precious shall their blood be in his sight; he will not be prodigal of the lives of his subjects, casting them away merely to gratify his own revenge, or covetousness, or insatiable desire of enlarging his empire, as earthly kings commonly do, but, like a true father of his people, will tenderly preserve them, and severely avenge their blood upon those who shall shed it.
