1 Corinthians 10:16-18 World English Bible (WEB)
16 The cup of blessing which we bless, isn’t it a sharing of the blood of Christ? The bread which we break, isn’t it a sharing of the body of Christ? 17 Because there is one loaf of bread, we, who are many, are one body; for we all partake of the one loaf of bread. 18 Consider Israel according to the flesh. Don’t those who eat the sacrifices participate in the altar?
