12 Now Amasa wallowed in blood in the midst of the highway. And when the man saw that all the people stood still, he removed Amasa out of the highway into the field, and cast a cloth upon him, when he saw that every one that came by stood still.
Joab barbarously murdered Amasa. The more plot there is in a sin, the worse it is. Joab contentedly sacrificed the interest both of the king and the kingdom to his personal revenge. But one would wonder with what face a murderer could pursue a traitor; and how, under such a load of guilt, he had courage to enter upon danger: his conscience was seared.
