Jason, a High Priest in the Temple in Jerusalem, was from the Onied Family and lived between 175-172 BCE.
The people who wrote about Jason lived around 300 BCE. The exhumation of bones and their placement in charnel piles was the norm. The best example of this practice is the tomb of Jason in western Jerusalem, where the earlier practice was actually discontinued and ossuary burial begun, according to L. I. Rahmani, between 20 and 15 BCE.
