MATTHEW 27:5 (cf. Acts 1:18)—Did Judas die by hanging or by falling on rocks?
PROBLEM: Matthew declares that Judas hanged himself. However, the Book of Acts says that he fell and his body burst open.
SOLUTION: These accounts are not contradictory, but mutually complementary. Judas hung himself exactly as Matthew affirms that he did. The account in Acts simply adds that Judas fell, and his body opened up at the middle and his intestines gushed out. This is the very thing one would expect of someone who hanged himself from a tree over a cliff and fell on sharp rocks below.
