teach a righteous person and he will add to his learning.

Proverbs 25:12

25:12 Like an earring of gold and an ornament of fine gold,

so is a wise reprover to the ear of the one who listens.

141:5 May the godly strike me in love and correct me!

May my head not refuse choice oil!

Indeed, my prayer is a witness against their evil deeds.
