In any case, I must press on today and tomorrow and the next day – for surely no prophet can die outside Jerusalem! (NIV)
Nevertheless, I must continue on My way today and tomorrow and the day after that--for it will never do for a prophet to be destroyed away from Jerusalem! (AMP)
Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem. (KJV)
