1 Korintus 10:21

10:21 You cannot drink the cup of the Lord and the cup of demons. You cannot take part in the table of the Lord and the table of demons.

1 Korintus 14:23

14:23 So if the whole church comes together and all speak in tongues, and unbelievers or uninformed people enter, will they not say that you have lost your minds?

1 Korintus 7:5

7:5 Do not deprive each other, except by mutual agreement for a specified time, so that you may devote yourselves to prayer. ¹  Then resume your relationship, ²  so that Satan may not tempt you because of your lack of self-control.

[7:5]  ¹ tc Most later witnesses (א² Ï sy) add “fasting and” (τῇ νηστείᾳ καί, th nhsteia kai) before “prayer.” But such an addition is motivated by ascetic concerns; further, its lack in Ì^11vid,46 א* A B C D F G P Ψ 33 1739 1881 2464 al latt co argues decisively against its authenticity.

[7:5]  ² tn Grk “and be together again.”
