Battle of Beth Zur
The Battle of Beth Zur was fought between the Maccabees led by Judas Maccabeus and a Seleucid Greek army led by Regent Lysias in October 164 BC at Beth Zur. According to the books of Maccabees, the rebels won the battle, although how significant this victory really was is disputed; it is possible the battle's result was inconclusive. Through a stroke of good fortune for the rebels, the days after the battle likely coincided with news of Seleucid King Antiochus IV Epiphanes's death reaching Judea; rather than continue the campaign, the Seleucid army and Lysias returned to the capital to handle the leadership transition. The Maccabees were able to capture Jerusalem soon after.
Primary sources
The Battle of Beth Zur is recorded in the books of 1 Maccabees, 2 Maccabees, and Josephus's Antiquities of the Jews Book 12, Chapter 7. The main point of divergence is timing: according to 1 Maccabees, Lysias initiated an expedition, was defeated at Beth Zur, Jerusalem was taken, the Second Temple was cleansed, Lysias makes a second expedition around 162 BC, and Beth Zur is again besieged by the Seleucids in the second expedition. Contrary to 1 Maccabees, 2 Maccabees indicates Lysias's expedition and the Battle of Beth Zur happened after the taking of Jerusalem and the purification of the Temple; this has caused some scholars such as Daniel R. Schwartz to believe that Lysias only made a single expedition to Judea, rather than the account in 1 Maccabees of two expeditions separated by two years. Still, the default stance of many historians of the revolt has been to prefer the 1 Maccabees version of events, as the author was writing closer in time to the events and was seemingly an eyewitness to at least part of the Revolt; additionally, some of the documents reproduced in 2 Maccabees seem to support the chronology of 1 Maccabees, as does the Book of Daniel.Josephus largely echoes 1 Maccabees, his main source, but adds that the Maccabees clashed with only the advance troops of the Seleucids, a reasonable and plausible addition.
Background
Toward the end of the summer of 165 BC, King Antiochus IV Epiphanes gathered forces from the western part of his empire to leave for an expedition to the eastern satrapies in Babylonia and Persia. There, he intended to stay awhile, replace or do battle with rebellious governors, deter the growing Parthian Empire from invading, and restore a flow of taxes to the capital. He left Lysias in charge as regent in the Seleucid capital Antioch and to raise his young son, the future Antiochus V. A Seleucid expedition to Judea was repelled in 165 BC, however, after the Maccabees won the Battle of Emmaus. The Western half of the Seleucid Empire was still deprived of many dependable Greek soldiers due to Antiochus IV's expedition to the eastern satrapies, so it appears that Lysias negotiated with the rebels for 6-9 months during the fall and winter of 165 BC and early 164 BC. Some of the documents recorded in 2 Maccabees may be communications from the time period, as Lysias offers a range of offers to placate the Maccabees. Historian Bezalel Bar-Kochva offers tentative suggestions for dates of the document in and being from late 165 BC, and being from spring of 164 BC, a conditional amnesty offered at the request of High Priest Menelaus.However, it seems negotiations fell through, possibly after being rejected by Antiochus IV after messengers informed him of the Maccabees' demands. Lysias marshaled an army to restore order in the Judean countryside. His forces camped at Beth Zur, a fortified place near Jerusalem.
