Therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again, so that I will not cause them to fall. (NIV)
Therefore, if [my eating a] food is a cause of my brother's falling or of hindering [his spiritual advancement], I will not eat [such] flesh forever, lest I cause my brother to be tripped up and fall and to be offended. (AMP)
Wherefore, if meat make my brother to offend, I will eat no flesh while the world standeth, lest I make my brother to offend. (KJV)
