201 There happened to be a troublemaker there named Sheba son of Bicri, a man from the tribe of Benjamin. Sheba blew a ram's horn and began to chant: "Down with the dynasty of David! We have no interest in the son of Jesse. Come on, you men of Israel, back to your homes!" 2 So all the men of Israel deserted David and followed Sheba son of Bicri. But the men of Judah stayed with their king and escorted him from the Jordan River to Jerusalem. 3 When David came to his palace in Jerusalem, he took the ten concubines he had left to look after the palace and placed them in seclusion. Their needs were provided for, but he no longer slept with them. So each of them lived like a widow until she died.
4 Then the king told Amasa, "Mobilize the army of Judah within three days, and report back at that time." 5 So Amasa went out to notify Judah, but it took him longer than the time he had been given. 6 Then David said to Abishai, "Sheba son of Bicri is going to hurt us more than Absalom did. Quick, take my troops and chase after him before he gets into a fortified town where we can't reach him." 7 So Abishai and Joab, together with the king's bodyguard and all the mighty warriors, set out from Jerusalem to go after Sheba. 8 As they arrived at the great stone in Gibeon, Amasa met them. Joab was wearing his military tunic with a dagger strapped to his belt. As he stepped forward to greet Amasa, he slipped the dagger from its sheath. 9 "How are you, my cousin?" Joab said and took him by the beard with his right hand as though to kiss him.

Commentary on 2 Samuel 20:1-3
(Read 2 Samuel 20:1-3)
One trial arises after another for our good, till we reach the place where sin and sorrow are for ever done away. Angry disputers misunderstand or misconstrue one another's words; proud men will have every thing their own way, or wholly refuse their assistance. The favour of the many is not to be depended upon; and what have others to expect, when Hosanna to the Son of David was soon changed to Crucify him, crucify him?
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.
