זֵ֣כֶר צַ֭דִּיק לִבְרָכָ֑ה וְשֵׁ֖ם רְשָׁעִ֣ים יִרְקָֽב׃
義人的名聲必蒙祝福；惡人的名字必朽爛。
Rashi
The mention of a righteous man is for a blessing Whoever mentions a righteous man blesses him.
Rashi
but the name of the wicked shall rot Decay develops in their name, for no one wishes to mention his [the wicked man’s] name, and it is automatically forgotten.
