Potter's Field

Otherwise known as a pauper's graveyard. The origin of the term comes from Matthew 27:7, in which the gold given to Judas, then returned, was used to purchase land to be used as a graveyard for indigent, anonymous, or other people without any other means for interment:

27:5 And he threw the pieces of silver into the temple sanctuary and departed; and he went away and hanged himself.

27:6 The chief priests took the pieces of silver and said, "It is not lawful to put them into the temple treasury, since it is the price of blood."

27:7 And they conferred together and with the money bought the potter's field as a burial place for strangers.
