1 Corinthians 10:16-18 Modern English Version (MEV)
16 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? 17 For we, being many, are one bread and one body, for we are all partakers of that one bread.
18 Consider Israel after the flesh: Are not those who eat of the sacrifices partakers of the altar?
