מַ֥עֲדֶה בֶּ֨גֶד ׀ בְּי֣וֹם קָ֭רָה חֹ֣מֶץ עַל־נָ֑תֶר וְשָׁ֥ר בַּ֝שִּׁרִ֗ים עַ֣ל לֶב־רָֽע׃ (פ)
Seperti orang yang menanggalkan pakaian pada hari yang dingin, dan seperti cuka yang dituangkan ke atas kapur, demikianlah orang yang menyanyikan lagu-lagu bagi hati yang sedih.
Rashi
A worn-out garment on a cold day Heb. מעדה בגד, synonymous with (Isa. 64:5): “בגד עדים, a discarded garment,” a worn-out garment that is fit to be taken off since it is worn out, as we translate into Aramaic “ויסר” (Ex. 7:24) as ויעדי, and He shall remove. Now this is its interpretation: A worn-out garment on a cold day is like vinegar on chalk. chalk Heb. נתר, a kind of soft earth, like our earth that is called creide, which they would hew and make vessels therefrom, and if vinegar falls on it, [the earth] is dissolved and ruined. So... is one who sings songs to a broken heart [lit. on a bad heart. This one] resembles them both. Now what is one who sings songs? This is one who teaches the Torah to a wicked student, who has no intention in his heart to fulfill it.
