The corresponding letter to this chapter is Resh – wickedness; the wicked.
Sh'mu'el Bet 20:1 Now a worthless fellow happened to be there whose name was Sheva, the son of Bikhri, a Binyamini; and he blew the trumpet and said, "We have no portion in David, Nor do we have inheritance in the son of Yishai; Every man to his tents, O Israel!"
This is a lot like those who want no portion in the son of David –Yeshua.
worthless fellow – Boy what a title to be given! Not to mention that it is in the Bible and for thousands of years people have read that he was worthless. Don’t let it be said of you that you are a worthless fellow.
Sh'mu'el Bet 20:2-3 So all the men of Israel withdrew from following David, and followed Sheva the son of Bikhri; but the men of Y’hudah remained steadfast to their king, from the Yarden even to Yerushalayim. Then David came to his house at Yerushalayim, and the king took the ten women, the concubines whom he had left to keep the house, and placed them under guard and provided them with sustenance, but did not go in to them. So they were shut up until the day of their death, living as widows.
Many generations whom have rejected the Messiah have kept the little children from being spiritually renewed to the Father through the Son of David- Yeshua.
Sh'mu'el Bet 20:4-6 Then the king said to Amasa, "Call out the men of Y’hudah for me within three days, and be present here yourself." So Amasa went to call out the men of Y’hudah, but he delayed longer than the set time which he had appointed him. And David said to Avishai, "Now Sheva the son of Bikhri will do us more harm than Avshalom; take your lord's servants and pursue him, lest he find for himself fortified cities and escape from our sight."
Delaying to follow the king’s command put the kingdom in jeopardy. Acting in a timely manner before Sheva could rally additional support was very important.
Sh'mu'el Bet 20:7-10 So Yo’av's men went out after him, along with the K’reti and the P’leti and all the mighty men; and they went out from Yerushalayim to pursue Sheva the son of Bikhri. When they were at the large stone which is in Giv’on, Amasa came to meet them. Now Yo’av was dressed in his military attire, and over it was a belt with a sword in its sheath fastened at his waist; and as he went forward, it fell out. And Yo’av said to Amasa, "Is it well with you, my brother?" And Yo’av took Amasa by the beard with his right hand to kiss him. But Amasa was not on guard against the sword which was in Yo’av's hand so he struck him in the belly with it and poured out his inward parts on the ground, and did not strike him again; and he died. Then Yo’av and Avishai his brother pursued Sheva the son of Bichri.
Amasa was executed for not carrying out the king’s command. Amasa had been Avshalom’s general. Perhaps he was still interested in the downfall of David.
Sh'mu'el Bet 20:11-14 Now there stood by him one of Yo’av's young men, and said, "Whoever favors Yo’av and whoever is for David, let him follow Yo’av." But Amasa lay wallowing in his blood in the middle of the highway. And when the man saw that all the people stood still, he removed Amasa from the highway into the field and threw a garment over him when he saw that everyone who came by him stood still. As soon as he was removed from the highway, all the men passed on after Yo’av to pursue Sheva the son of Bikhri. Now he went through all the tribes of Israel to Avel even to Beit-Ma’akhah and all the Berim; and they were gathered together and also went after him.
Yo’av appears to be a hardhearted guy. But I think he was patriotic and was doing what he believe was best for the country.
Sh'mu'el Bet 20:15-25 And they came and besieged him in Avel Beit-Ma’akhah, and they cast up a mound against the city, and it stood by the rampart; and all the people who were with Yo’av were wreaking destruction in order to topple the wall. Then a wise woman called from the city, "Hear, hear! Please tell Yo’av, 'Come here that I may speak with you.'" So he approached her, and the woman said, "Are you Yo’av?" And he answered, "I am." Then she said to him, "Listen to the words of your maidservant." And he answered, "I am listening." Then she spoke, saying, "Formerly they used to say, 'They will surely ask advice at Avel,' and thus they ended the dispute. I am of those who are peaceable and faithful in Israel. You are seeking to destroy a city, even a mother in Israel. Why would you swallow up the inheritance of the L-RD?" And Yo’av answered and said, "Far be it, far be it from me that I should swallow up or destroy! "Such is not the case. But a man from the hill country of Efrayim, Sheva the son of Bikhri by name, has lifted up his hand against King David. Only hand him over, and I will depart from the city." And the woman said to Yo’av, "Look, his head will be thrown to you over the wall." Then the woman wisely came to all the people. And they cut off the head of Sheva the son of Bikhri and threw it to Yo’av. So he blew the trumpet, and they were dispersed from the city, each to his tent. Yo’av also returned to the king at Yerushalayim. Now Yo’av was over the whole army of Israel, and B’nayah the son of Y’hoyada was over the K’reti and the P’leti; and Adoram was over the forced labor, and Y’hoshafat the son of Achilud was the recorder; and Sheva was scribe, and Tzadok and Evyatar were priests; and Ira the Ya’iri was also a priest to David.
A wise woman – she probably held some position of authority in the town. Because of her skillful negations she was able to spare the city from unnecessary bloodshed.
Those that go against the anointed eventually get cut off. Either you were for David and would be blessed by David or you were against David and would be cursed by going against David. Many today are either for Yeshua and will be blessed by Yeshua or those that are against him and will be cursed because they are against him. One only hurts themselves by not following the anointed. The choice is theirs.
