Did the priests buy the field or did Judas? Either way, both state it was bought with the money he was given. They both mention the potter's field becoming known as the field of blood, as well as Judas dying a violent death.
Nope, the accounts are radically different - in one Judas simply hangs himself, committing suicide which is a perfectly plausible explanation for someone who may be wracked with remorse, requiring no kind of divine intervention. In the other account Judas when buying the land with the money he'd received was immediately struck down - 'falling headfirst he burst open in the middle and all his intestines gushed out', in other words some kind of direct and violent divine retribution.
And there are also discrepancies as to who bought the land - in Matthew it is the jewish authorities while in Acts it is Judas himself.
What is clear in both accounts is that this cements the notion of 'blood money' a slur used to support persecution of jewish people for thousands of years.
