Field of Blood

And it was known to all that dwell in Jerusalem; so that in their own language that field was called Akeldama, that is, Field of Blood.

Acts 1:19

BLOOD referred the text is INNOCENT BLOOD of Christ.

Just compare with the story of the Evangelist Matthew:

Then Judas, which had betrayed him, seeing that he was condemned, brought, sorry, the thirty pieces of silver to the chief priests and elders,

Saying: I have betrayed innocent blood. But they said, is that to us? That's up to you.

And he cast down the pieces of silver in the temple, and departed, and was to hang.

And the chief priests took the silver pieces, and said: It is not lawful to put them into the treasury, because they are the price of blood.

And took counsel, and bought with them the field of a potter, to bury strangers.

Therefore that field was called, to this day, Field of Blood.

Then was fulfilled what vaticinara the prophet Jeremiah took the thirty pieces of silver, the price of which was valued, whom they children of Israel;

And gave them for the potter's field, according to what the Lord commanded me

Matthew 27: 2-10
