201 Now a scoundrel named Sheba son of Bichri, a Benjaminite, happened to be there. He sounded the trumpet and cried out, "We have no portion in David, no share in the son of Jesse! Everyone to your tents, O Israel!" 2 So all the people of Israel withdrew from David and followed Sheba son of Bichri; but the people of Judah followed their king steadfastly from the Jordan to Jerusalem. 3 David came to his house at Jerusalem; and the king took the ten concubines whom he had left to look after the house, and put them in a house under guard, and provided for them, but did not go in to them. So they were shut up until the day of their death, living as if in widowhood.
4 Then the king said to Amasa, "Call the men of Judah together to me within three days, and be here yourself." 5 So Amasa went to summon Judah; but he delayed beyond the set time that had been appointed him. 6 David said to Abishai, "Now Sheba son of Bichri will do us more harm than Absalom; take your lord's servants and pursue him, or he will find fortified cities for himself, and escape from us." 7 Joab's men went out after him, along with the Cherethites, the Pelethites, and all the warriors; they went out from Jerusalem to pursue Sheba son of Bichri. 8 When they were at the large stone that is in Gibeon, Amasa came to meet them. Now Joab was wearing a soldier's garment and over it was a belt with a sword in its sheath fastened at his waist; as he went forward it fell out. 9 Joab said to Amasa, "Is it well with you, my brother?" And Joab took Amasa by the beard with his right hand 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.
