1 Corinthians 10:16-18

Young's Literal Translation

¹⁶ The cup of the blessing that we bless -- is it not the fellowship of the blood of the Christ? the bread that we break -- is it not the fellowship of the body of the Christ?

¹⁷ because one bread, one body, are we the many -- for we all of the one bread do partake.

¹⁸ See Israel according to the flesh! are not those eating the sacrifices in the fellowship of the altar?
