Matthew 27:3-10 CSB
Then Judas, his betrayer, seeing that Jesus had been condemned, was full of remorse and returned the thirty pieces of silver to the chief priests and elders. “I have sinned by betraying innocent blood,” he said.
“What’s that to us?” they said. “See to it yourself!” So he threw the silver into the temple and departed. Then he went and hanged himself.
The chief priests took the silver and said, “It’s not permitted to put it into the temple treasury, since it is blood money.” They conferred together and bought the potter’s field with it as a burial place for foreigners. Therefore that field has been called “Field of Blood” to this day. Then what was spoken through the prophet Jeremiah was fulfilled: They took the thirty pieces of silver, the price of him whose price was set by the Israelites, and they gave them for the potter’s field, as the Lord directed me.
