6 and David saith unto Abishai, 'Now doth Sheba son of Bichri do evil to us more than Absalom; thou, take the servants of thy lord, and pursue after him, lest he have found for himself fenced cities, and delivered himself 'from' our eye.'

Matthew Henry's Commentary on 2 Samuel 20:6

Commentary on 2 Samuel 20:4-13

(Read 2 Samuel 20:4-13)

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.
