6 And David said to Abi'shai, "Now Sheba the son of Bichri will do us more harm than Ab'salom; take your lord's servants and pursue him, lest he get himself fortified cities, and cause us trouble."

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.
