Josephus's Life is very dense with references to characters named Jesus or Justus. The entire work is mercifully brief, and I've prepared a verse-by-verse summary.
1 gives Josephus’ genealogy. He says he is descended from Jonathan son of Hasmoneus.
2 says that Josephus took training from Pharisees, Sadducees and Essenes, and apprenticed himself to Banus who lived in the desert. He chose to live according to the rules of the Pharisees.
3: Josephus goes to Rome, experiences a shipwreck, and meets Nero’s wife Poppea.
4-5: Josephus takes note of a developing rebellion. The high priests pretend to be of the same mind as the people, while actually hoping the Romans will put down the rebellion.
6: Cestius is defeated by the Jews. Other people of the region attack the Jews, forcing them to band together in solidarity.
7. Josephus is sent to Galilee to persuade the hotheads to disarm.
8. At Sepphoris, the people are allied with the Romans. Josephus allays their fears and placates the surrounding Galileeans.
9 describes Justus of Tiberias, son of Pistus, author of a history. He is trying to incite the citizens of Tiberius to fight against Sepphoris because the latter city has accomodated the Romans, and received favors as a result. Josephus says "As my narrative progresses I shall tell about this man's wicked character and lifestyle and how he and his brother were the main authors of our destruction.”
10 says that at Gischala, John son of Levi has maintained control, is allied with the Romans, and has fortified and rebuilt the city after rebel attacks.
11: At Gamala, the administrator Varus was killing Jews in hopes of being promoted to become King. The rightful king, Philip son of Jacimus, returned and put an end to persecution of Jews, but also continued Gamala’s allegiance with the Romans.
12. Josephus and his colleagues from the Sanhedrin approached Justus of Tiberias and asked him to demolish a temple. Jesus son of Sapphias, "whom we have already mentioned as the leader of a faction of mariners and poor people” (where was this already mentioned?) beat them to it, setting the palace on fire and looting it.
13. Josephus recovers remaining goods from the burned temple at Tiberias. Then he goes to visit John of Gischala. John is profiteering by seizing corn stores, and by buying oil in Gischala and selling it in blockaded Caesarea Philippi.
14. Josephus hires brigands to be mercenaries, and uses them to keep peace.
15-19 John of Gischala foments revolt in Tiberias, joined by Justus and Pistus. Josephus puts down the revolt, but deals mercifully with the rebels, although they tried to kill him.
20-21 John asks forgiveness. Josephus goes to Sepphoris.
22 People of Sepphoris send to Jesus warlord of brigands in the borders of Ptolemais. He attacks with his gang. Josephus traps Jesus, but lets him reassemble his troops.
23-24. Agrippa sends an army to destroy the Gamala fortress. Ebutius and Josephus engage and then avoid combat.
25. John son of Levi continues to foment rebellion against Josephus.
26. Procurator Ptolemy is ambushed by brigands. Josephus tricks them, takes the plunder and returns it to Ptolemy.
27. Jesus son of Sapphias (a ruler in Tiberias) a revolutionary, calls for rebellion against Josephus because of this trickery.
28-29 Josephus dresses in black to appear pitiful, and lies again about his intent for the plunder. A dispute arises between factions, and Josephus escapes.
30 Josephus intimidates his opponents by scourging and cutting off the hand of one of the boldest of them.
31 Josephus sends a house of nobles from Tarichea on a boat to Hippos.
32-33 The Tiberians want to ally with the king. Josephus goes to Tarichea, bringing back some boats to Tiberias. The Tiberians were afraid of Josephus’s ships, and so they maintained their allegiance with him.
34. Josephus punishes “the author of this rebellion, named Cleitus”.
35. Josephus warns Justus of Tiberias and his father Pistus, and then lets them loose. Josephus mentions that the people of Gamala have cut off Justus’s brother’s hands, and executed a Jesus who was the husband of the sister of a person named Justus who was the brother of Chares, one of Philip’s kinsmen.
36. Philip son of Jacimus returns to Gamala, as instructed by Agrippa.
37, Here Josephus tells the story of a rebellion in Gamala, led by “Joseph the midwife’s son”. They are the ones who killed Chares, his kinsman Jesus, brother of Justus of Tiberias (?). Josephus builds fortifications.
38. John son of Levi of Gischala, sends Simon his brother to Jerusalem. Simon consults with Simon son of Gamaliel. Simon son of Gamaliel consults with Ananus, and Jesus the son of Gamala. They decide to clip Josephus’s wings.
39. Simon, and John’s brother, bribe high priest Artanus, who had supported Josephus. They agree to send a deputation consisting of Jonathan, Ananias (humble pharisees), and Jozar and Simon, of priestly stock. Their goal: to turn the people away from Josephus.
40. Jonathan and his deputation receive 40,000 pieces of silver from the public treasury. They send for a Galilean named Jesus who is currently in Jerusalem with 600 soldiers.
41. Jesus son of Gamalas, a friend and companion of Josephus, notifies Josephus’s father of the plot. Josephus wants to go home, but the people persuade him to stay.
42. Josephus has a vision in a dream, telling him to fight the Romans.
43. Josephus gathers an army, and goes to pretend to fight Placidus near Ptolemais.
44-47 Josephus jockeys for position against Jonathan.
48 Jonathan retreats to a castle owned by Jesus. The Galileans support Josephus against Jonathan.
49 Josephus proclaims his virtue, and negotiates with Jonathan.
50 Josephus exposes Jonathan as a traitor to Josephus.
51. Josephus takes the people to Sogane to prevent them killing Jonathan.
52. Josephus sends emissaries to Jerusalem.
53. Jonathan goes to Tiberias, expecting a welcome from Jesus the governor. But, Jesus has been replaced by Silas. Silas summons Josephus.
54. Jonathan, Jesus and Justus plot with the citizens of Tiberias against Josephus.
55. The group answers a fake call to arms against non-existant Romans.
56. Returning, Ananias proposes a public fast without weapons. John plots to bring armed soldiers to capture Josephus. Josephus brings daggars to the fast.
57. Jesus asks Josephus what happened to his plundered gold and silver.
58-62 Josephus maneuvers to capture Jonathan and his friends.
63-64 Josephus sends Jonathan, Ananias, Simon and Joazar to Jerusalem for sentencing.
65 Josephus rants against inaccuracies in Justus’s history of the war, which has just been published. He asserts that his history (JW) is better.
66. Josephus threatens John’s followers, who abandon him to join Josephus.
67. Sepphoris applies to Cestius Gallus for protection.
68. Galileans are outraged against Sepphoris and also Tiberias because of disloyalty.
69. Josephus saves Tiberias from the Galileans, by making an eloquent speech.
70. Justus son of Pistus flees to the king, in fear that the Tiberians prefer Josephus.
71. Josephus battles the Romans at Sepphoris.
72. Josephus is injured in battle at Capernaum, and sent to Tarichea.
73-74 Vespasian arrives, and the reader is referred to JW for the rest of the story.
75. Josephus collaborates with Vespasian and Titus, and is given the holy books. Returning from Thecoa, he recognizes three captives being crucified; he pleads with Titus for their lives; two perish, one survives.
76-80 Josephus continues to prosper under the care of Vespasian, Titus and Domitian. The treatise is dedicated to Epaphroditus.
