New Defender's Study Bible Notes
1:18 purchased a field. By comparison with the account in Matthew 27:3-8, it is evident that Judas “purchased” this field only indirectly. He threw down his “blood money” (the thirty pieces of silver paid him for betraying Jesus) in front of the chief priests, who used it to buy the field called Aceldama (Acts 1:19), or “the field of blood” (Matthew 27:8). He then hanged himself, apparently in the same field, but bungled the attempt, actually dying as described in this verse.
