1 Corinthians 11:28-30 English Standard Version (ESV)
28 Let a person examine himself, then, and so eat of the bread and drink of the cup. 29 For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. 30 That is why many of you are weak and ill, and some have died.[a]
Kehillah in Corinth I 11:28-30 Orthodox Jewish Bible (OJB)
28 But let a ben Adam apply cheshbon hanefesh to himself and in that manner let him eat of the Pesach matzoh and let him drink of the Pesach Kiddush Cup.
29 For the one eating and drinking is the one eating and drinking mishpat to himself when not discerning the basar (body).
30 Because of this, many among you are weak and there are cholim (sick) and a number are sleeping the sleep of the mesim.
