I want to know the answer to the following question:
Was Jesus in the tomb exactly 72 hours?
All the background I'm provided with is that "Others have countered by saying that this ignores the Jewish idiom by which a "day and night" may refer to any part of a 24-hour period, that the expression in Matthew is idiomatic, not a statement that Jesus was 72 hours in the tomb, and that the many references to a resurrection on the third day do not require three literal nights.". Is that enough to answer the question?
Answer: yes
