Matthew 27:5 ASV

³  Then Judas, who betrayed him, when he saw that he was condemned, repented himself, and brought back the thirty pieces of silver to the chief priests and elders,

⁴  saying, I have sinned in that I betrayed innocent blood. But they said, What is that to us? see thou 'to it'.

⁵  And he cast down the pieces of silver into the sanctuary, and departed; and he went away and hanged himself.

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

⁷  And they took counsel, and bought with them the potter's field, to bury strangers in.
