Proverbs 17:21
Thomson 1808
A father hath no joy in an unteachable son: but a prudent son is the joy of his mother.
Brenton 1851
and the heart of a fool is grief to its possessor. A father rejoices not over an uninstructed son; but a wise son gladdens his mother.
Greek · Brenton
καρδία δὲ ἄφρονος ὀδύνη τῷ κεκτημένῳ αὐτήν· οὐκ εὐφραίνεται πατὴρ ἐφʼ υἱῷ ἀπαιδεύτῳ, υἱὸς δὲ φρόνιμος εὐφραίνει μητέρα αὐτοῦ.
