Matthew 27:5-8
27:5 So Judas threw the silver coins into the temple and left. Then he went out and hanged himself.
27:6 The chief priests took the silver and said, “It is not lawful to put this into the temple treasury, since it is blood money.”
27:7 After consulting together they bought the Potter’s Field with it, as a burial place for foreigners.
27:8 For this reason that field has been called the “Field of Blood” to this day.
