Which Preposition is Used Concerning Paul’s Body in Galatians 6:17?

KJV

From henceforth let no man trouble me: for I bear in my body the marks of the Lord Jesus.

NIV (and others)

From now on, let no one cause me trouble, for I bear on my body the marks of Jesus.

What does the original language literally say? (On), or (in)
the body?

I’m not asking for an exegesis, I’m asking for a literal translation.
