Loosely speaking, there are three main branches to take with these references to the Hasideans as to who they were.
Unorganized faithful The simplest option is to deny that the Hasideans were a coherent group at all. In this case, 1 Maccabees was merely expressing that some of the "faithful" of Israel joined with Mattathias, and other "faithful" were content to negotiate with Alcimus (if unwisely according to the author of 1 Maccabees). They would not be greatly distinguished from any other traditionalist Jews.
Daniel R. Schwartz notes that 1 Maccabees 2:42 has significant textual variants between the oldest manuscripts. The
Codex Alexandrinus, the
Vulgate Latin translation, and Syriac translations read "Hasideans" (, ); however, the
Codex Sinaiticus, the
Venetus, and Old Latin translations only read "Judeans" (, ) instead. Schwartz prefers the "Judeans" reading which would eliminate mention of the Hasideans there entirely, and suggests that a translator from Hebrew to Greek may have simply erred when choosing to transliterate the Hebrew
hasidim as if it were a proper name, or some other scribal meddling.
A group of zealous warriors Another option is to consider them a group who indeed took the proper name
hasidim or a variant thereof, but a group largely in sync with Judas Maccabeus and the Hasmoneans, if possibly extra-pious. In this version, the Hasideans were a distinct group that allied with Judas early and remained so during the revolt. The incident described in 1 Maccabees 7 was not a major split or philosophical difference, but a tactical one. The Maccabees had been crushingly defeated at the
Battle of Beth Zechariah in 162 BCE, had declined to interfere with Bacchides' campaign in 161 BCE, and were likely still rebuilding. The Hasideans had been true allies of Judas, but some of them had hoped to negotiate for concessions and relief thinking Alcimus a moderate, and the government used the opportunity to execute those who showed up. Still, in this scenario, the government was correct in perceiving the Hasideans as opponents. Judas declined to negotiate personally, deciding it was not good to negotiate from a position of weakness, and he would need to win again on the battlefield before a longer-term peace could be secured. In this view, the incident proved him correct: negotiations undertaken before the rebels held more ground would only result in their defeat.
Jewish moderates The third option is to see the Hasideans as a group but with a distinctly different ideology than the Hasmoneans; the passage in 1 Maccabees 7 was recording a genuine difference in goals. In this view, the Hasideans were deeply religious but comparative "moderates" as their chief concern was the repeal of Antiochus IV's decrees forbidding Jewish practices. They had joined with Judas earlier due to the anti-Jewish persecution and their anger at the corruption of High Priest
Menelaus. After these decrees were repealed in 163–162 BCE, however, fighting a full-scale rebellion against the Seleucid government was no longer seen as needed. The hated High Priest Menelaus was executed around 162 BCE. This explains how Alcimus was able to lure some Hasideans to his side: by offering a return to the status quo ante and peace, when Judaism was accepted but the authority of the Seleucid government was unchallenged. While the above two views largely take 1 Maccabees at its word (if differing on what those words imply), this view can take into account more skeptical stances that distrust 1 Maccabees as a partisan, pro-Hasmonean source. To continue the revolt, the Hasmoneans had to convince the moderates that the Seleucids were evil and to be hated; they were a looming threat that could not be ignored. A story such as the one seen in Chapter 7, where the perfidious Alcimus executes even supposed moderates and breaks his oaths, would fit perfectly into the Hasmonean ideology that the only sure path for Judea was to unite under the Hasmonean banner. As such, the details cannot be trusted to be historical in this view, with the Hasmoneans potentially exaggerating or misrepresenting a real incident to become a symbol of Seleucid untrustworthiness.
Problems of historiography An alternative approach is to be modest on what can be known. Some historians believe that there is simply nothing to say about the Hasideans until more information than the three passages we have is discovered.
John J. Collins was disdainful of the hypothesizing done by other scholars; he wrote in 1977 that the Hasideans "had grown in recent scholarship from an extremely poorly attested entity to the great Jewish alternative to the Maccabees at the time of the revolt. There has been no corresponding growth in the evidence." ==Later influence==
