“The rest of the acts of John, his wars, and the brave deeds that he did, as well as the building of the walls and his other achievements, are written in the annals of his high priesthood, from the time that he became high priest after his father.”
This is the stylistic form similar to that of 1and 2 Kings. However, there is no mention of his death. This story ends around 134 BCE. There is no indication of what happened to John and his family. The annals, of course, have been lost. Apparently, he was the high priest from 134-104 BCE. The whole story of the Maccabees ends abruptly without any real resolution. There is no great ending to this story.
