Proverbs
Proverbs 31:18
The verse from Eishet Chayil reads: 'Her lamp does not go out at night' — traditionally interpreted as a reference to the Shabbat candles kindled by the woman of valor, whose light endures through the night.
טָ֭עֲמָה כִּי־ט֣וֹב סַחְרָ֑הּ לֹא־יִכְבֶּ֖ה (בליל) [בַלַּ֣יְלָה] נֵרָֽהּ׃
ט She sees that her business thrives; Her lamp never goes out at night.
Why it matters — A classic biblical verse linked by the Sages and commentators to the mitzvah of Shabbat candle-lighting as an expression of the woman of valor.
