[31:18] 1 tn The first word of the ninth line begins with ט (tet), the ninth letter of the Hebrew alphabet.
[31:18] 2 sn The line may be taken literally to mean that she is industrious throughout the night (“burning the midnight oil”) when she must in order to follow through a business deal (W. McKane, Proverbs [OTL], 668); cf. TEV. But the line could also be taken figuratively, comparing “her light” to the prosperity of her household – her whole life – which continues night and day.
