*nerd voice* Ackshully, there is much debate about whether Roman crucifixions nailed the hands or the wrists. Experiments on cadavers in the 1930s concluded that a nail through the palm could not support the upper body.

However, nailing the heels in addition to the palms may have been enough to hold up the body. They could have also used rope to add support.

Nailing the palms would have been more painful, so they may have put in the extra work just to make the experience more torturous.

That said, biblical translations of "hand" could also include the wrist. And since Roman soldiers probably did not want bodies falling off the cross prematurely, it would make sense they would choose the more robust nailing location.

So we don't actually know where Jesus' holes are.

It is a hole-y mystery.
