1 Korintus 3:2

3:2 I fed you milk, ¹  not solid food, for you were not yet ready. In fact, you are still not ready,

1 Korintus 16:11

16:11 So then, let no one treat him with contempt. But send him on his way in peace so that he may come to me. For I am expecting him with the brothers. ² 

[3:2]  ¹ sn Milk refers figuratively to basic or elementary Christian teaching. Paul’s point was that the Corinthian believers he was writing to here were not mature enough to receive more advanced teaching. This was not a problem at the time, when they were recent converts, but the problem now is that they are still not ready.

[16:11]  ² tn Since Paul appears to expect specific delegates here and they were most likely men, the Greek word ἀδελφοί (adelfoi) here has not been not translated as “brothers and sisters.”
