Matthew 18:6-7 New King James Version (NKJV)
Jesus Warns of Offenses
6 “But whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea. 7 Woe to the world because of [a]offenses! For offenses must come, but woe to that man by whom the offense comes!
