Luke inserted these verses assuming his readers were unfamiliar with Judas" death and did not know Aramaic, the language spoken in Palestine in the first century. This helps us understand for whom he wrote this book. Judas purchased the "Field of Blood" indirectly by returning the money he received for betraying Jesus to the priests who used it to buy the field ( Matthew 27:3-10). Perhaps the name "field of blood" was the nickname the residents of Jerusalem gave it since "blood money" had purchased it. [source][source][source]
This account of Judas" death differs from Matthew"s who wrote that Judas hanged himself ( Matthew 27:5). Undoubtedly both accounts were true. Perhaps Judas hanged himself and in the process also fell (lit. flat on his face) and tore open his abdomen. Perhaps the rope or branch with which he hanged himself broke. Perhaps when others cut his corpse down it fell and broke open as Luke described. The traditional location of Hakeldama is southeast of Jerusalem near where the Hinnom and Kidron Valleys meet. This description of Judas" death stressed the awfulness of that apostle"s situation. It was Judas" defection, which led to his horrible death, and not just his death, that led to the need for a successor. Matthias succeeded Judas because Judas had been unfaithful, not just because he had died. Thus this text provides no support for the view that Christ intended one apostle to succeed another when the preceding one died. We have no record that when the apostle James died ( Acts 12:1-2) anyone succeeded him. [source][source][source]
