1 Corinthians 11:26-28
26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
ὁσάκις γὰρ ἂν ἐσθίητε τὸν ἄρτον τοῦτον καὶ τὸ ποτήριον τοῦτο πίνητε τὸν θάνατον τοῦ κυρίου καταγγέλλετε ἄχρις οὗ ἂν ἔλθῃ
27 Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
Ὥστε ὃς ἂν ἐσθίῃ τὸν ἄρτον τοῦτον ἢ πίνῃ τὸ ποτήριον τοῦ κυρίου ἀναξίως ἔνοχος ἔσται τοῦ σώματος καὶ αἵματος τοῦ κυρίου
28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
δοκιμαζέτω δὲ ἄνθρωπος ἑαυτόν καὶ οὕτως ἐκ τοῦ ἄρτου ἐσθιέτω καὶ ἐκ τοῦ ποτηρίου πινέτω·
