Ephesians 6:4-παιδείᾳ καὶ νουθεσίᾳ Κυρίου

Καὶ οἱ πατέρες, μὴ παροργίζετε τὰ τέκνα ὑμῶν, ἀλλὰ ἐκτρέφετε αὐτὰ ἐν παιδείᾳ καὶ νουθεσίᾳ Κυρίου (Ephesians 6:4 WH)

Observations from Charles Hodge's Commentary on Ephesians:

"Παιδείᾳ is a comprehensive word; it means the training or education of a child, including the whole process of instruction and discipline. Νουθεσίᾳ, from νουθετέω (νοῦς, τίθημι) to put in mind, is included under the more general term, and is correctly rendered admonition. It is the act of reminding one of his faults or duties. Children are not to be allowed to grow up without care or control. They are to be instructed, disciplined, and admonished, so that they be brought to knowledge, self-control, and obedience."

An additional insight from Vincent's Word Studies:

"Νουθεσία admonition occurs only here, 1 Corinthians 10:11, and Titus 3:10. The kindred verb νουθετέω to warn or admonish, is found only in Paul's letters, with the single exception of Acts 20:31 (see note). Its distinctive feature is training by word of mouth, as is shown by its classical usage in connection with words meaning to exhort or teach. Xenophon uses the phrase νουθετικοὶ λόγοι admonitory words. Yet it may include monition by deed."

Compare Deuteronomy 6:6-9.
