כִּ֤י אֶ֥ת אֲשֶׁ֣ר יֶאֱהַ֣ב יְהוָ֣ה יוֹכִ֑יחַ וּ֝כְאָ֗ב אֶת־בֵּ֥ן יִרְצֶֽה׃
car celui qu’il aime, l’Éternel le châtie, tel un père le fils qui lui est cher.
Rashi on Proverbs
as a father placates his son He desires to benefit his son and he placates him after striking him with the staff. So will the benefit be pleasant to you after the smiting.
