But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.
If you are not disciplined — and everyone undergoes discipline — then you are not legitimate, not true sons and daughters at all.
Εἰ δὲ χωρίς ἐστε παιδείας, ἧς μέτοχοι γεγόνασιν πάντες, ἄρα νόθοι ἐστὲ καὶ οὐχ υἱοί.
Ei de chōris este paideias, ēs metochoi gegonasin pantes, ara nothoi este kai oych yioi.
