1 Corinthians 11:27-29

Complete Jewish Bible

²⁷ Therefore, whoever eats the Lord’s bread or drinks the Lord’s cup in an unworthy manner will be guilty of desecrating the body and blood of the Lord! ²⁸ So let a person examine himself first, and then he may eat of the bread and drink from the cup; ²⁹ for a person who eats and drinks without recognizing the body eats and drinks judgment upon himself.
