1 Corinthians 10:16-18 Young's Literal Translation (YLT)
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?
