Josephus Antiquities 13.[5.9].171-173.

9. At this time there were three sects among the Jews, who had different opinions concerning human actions; the
one was called the sect of the Pharisees, another the sect of the Sadducees, and the other the sect of the Essens.
Now for the Pharisees, (11) they say that some actions, but not all, are the work of fate, and some of them are in
our own power, and that they are liable to fate, but are not caused by fate. But the sect of the Essens affirm, that
fate governs all things, and that nothing befalls men but what is according to its determination. And for the
Sadducees, they take away fate, and say there is no such thing, and that the events of human affairs are not at its
disposal; but they suppose that all our actions are in our own power, so that we are ourselves the causes of what
is good, and receive what is evil from our own folly. However, I have given a more exact account of these
opinions in the second book of the Jewish War.
