The Bible does not indicate what kind of wood that the cross is
made of. Furthermore, the cross could not have been made from a
dogwood tree because dogwood trees do not grow in Israel.
In what Bible verse does Jesus explain things to a man?
You'll need to be more specific to find the verse of what you are looking for because Jesus is explaining things to thousands of men and women before he was crucified. 'What was being explained' would be a helpful question to start with.
