1 Corinthians 11:28

28 Examine yourselves, and only then eat of the bread and drink of the cup.

1 Corinthians 11:28 In-Context

26 For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes.
27 Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be answerable for the body and blood of the Lord.
28 Examine yourselves, and only then eat of the bread and drink of the cup.
29 For all who eat and drink without discerning the body, eat and drink judgment against themselves.
30 For this reason many of you are weak and ill, and some have died.
