[20:20] 1 tn The form is the Piel participle of קָלַל (qalal), which means “to be light”; in the Piel stem it means “to take lightly; to treat as worthless; to treat contemptuously; to curse.” Under the Mosaic law such treatment of parents brought a death penalty (Exod 21:17; Lev 20:9; Deut 27:16).
[20:20] 2 tn “His lamp” is a figure known as hypocatastasis (an implied comparison) meaning “his life.” Cf. NLT “the lamp of your life”; TEV “your life will end like a lamp.”
[20:20] 3 tc The Kethib, followed by the LXX, Syriac, and Latin, has בְּאִישׁוֹן (bÿ’ishon), “in the pupil of the eye darkness,” the dark spot of the eye. But the Qere has בֶּאֱשׁוּן (be’eshun), probably to be rendered “pitch” or “blackest,” although the form occurs nowhere else. The meaning with either reading is approximately the same – deep darkness, which adds vividly to the figure of the lamp being snuffed out. This individual’s destruction will be total and final.
