KJV: Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
NASB: Therefore let us not judge one another anymore, but rather determine this-- not to put an obstacle or a stumbling block in a brother's way.
KJV: And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
NASB: and, "A STONE OF STUMBLING AND A ROCK OF OFFENSE"; for they stumble because they are disobedient to the word, and to this doom they were also appointed.
