This is Mark 7:19 from the NIV:

For it doesn’t go into their heart but into their stomach, and then out of the body.” (In saying this, Jesus declared all foods clean.)

Every time I see a parenthetical note in an ancient text, I feel like it was a later addition from a scribe.

Does our oldest manuscripts contain that part of the verse? Even it does, is there any reason to believe that it was a later addition?
