Matthew 27:5

2 and having bound him, they did lead away, and delivered him up to Pontius Pilate, the governor.

3 Then Judas -- he who delivered him up -- having seen that he was condemned, having repented, brought back the thirty silverlings to the chief priests, and to the elders, saying,

4 `I did sin, having delivered up innocent blood;` and they said, `What -- to us? thou shalt see!`

5 and having cast down the silverlings in the sanctuary, he departed, and having gone away, he did strangle himself.

6 And the chief priests having taken the silverlings, said, `It is not lawful to put them to the treasury, seeing it is the price of blood;`

7 and having taken counsel, they bought with them the field of the potter, for the burial of strangers;

8 therefore was that field called, `Field of blood,` unto this day.
