what does the bible say?
Scripture refers to Jesus’ crucifixion wounds as being in His hands (Psalm 22:16; Luke 24:39–40; John 20:25–27). John 19:36 states that none of Jesus’ bones were broken, yet the small bones of the palm would struggle to support a body’s weight, so scholars have questioned whether “hands” refers narrowly to the palm or more broadly includes the wrist area.
In the New Testament, the Greek word cheir (“hand”) functions more broadly than the English word “hand” and includes the wrist. For example, Peter’s cheir had been bound by chains (Acts 12:7), likely referring to his wrists. The same flexibility applies to the Hebrew word yad, used in Psalm 22:16. For example, it is used when bracelets were placed on Rebekah’s “hands” (Genesis 24:47 KJV), which would have been what we call “wrists.” In both ancient languages, the word was not restricted to just the palm and fingers.
Given that the wrists were included and that the wrist provides a stronger place to hang someone, it seems more likely that the nails went through the wrists, though we can’t be dogmatic about that conclusion.
