Reference for Genesis 41:60

The fire chamber was vaulted and it was a large room surrounded with stone projections, and the elders of the clan [serving in the Temple] used to sleep there, with the keys of the Temple courtyard in their hands. The priestly initiates used to place their bedding on the ground.

If a person plows from a pit full of bones, or from a heap of bones, Or from a field in which a grave had been lost, Or in which a grave was subsequently found, Or if he plows a field which was not his own, Or if a non-Jew plowed, he does not make a bet peras. For the rule of bet peras does not apply [even] to Samaritans.
