Hebrews 5:12
Nestle 1904 Greek New Testament · Berean Standard Bible
καὶ γὰρ ὀφείλοντες εἶναι διδάσκαλοι διὰ τὸν χρόνον πάλιν χρείαν ἔχετε τοῦ διδάσκειν ὑμᾶς τινα τὰ στοιχεῖα τῆς ἀρχῆς τῶν λογίων τοῦ Θεοῦ καὶ γεγόνατε χρείαν ἔχοντες γάλακτος καὶ οὐ στερεᾶς τροφῆς
Although by this time you ought to be teachers, you need someone to reteach you the basic principles of God’s word (note: Or of the oracles of God). You need milk, not solid food!
