² tn Or “profitable.” BDAG 960 s.v. συμφέρω 2.b.α has “τὰ συμφέροντα what advances your best interests or what is good for you Ac 20:20,” but the broader meaning (s.v. 2, “to be advantageous, help, confer a benefit, be profitable/useful”) is equally possible in this context.

¹ sn The seventh month was the month Tishri, according to the modern (Julian) calendar October 17, 520 b.c. The twenty-first day of Tishri marked the seventh day of the Feast of Tabernacles (Num 29:32-34). It also coincided with the date 440 years earlier (960 b.c.) when Solomon finished building his temple (1 Kgs 6:38; 8:2).

¹ tn Heb “in the day of your planting you [?].” The precise meaning of the verb תְּשַׂגְשֵׂגִי (tÿsagsegi) is unclear. It is sometimes derived from שׂוּג/סוּג (sug, “to fence in”; see BDB 691 s.v. II סוּג). In this case one could translate “you build a protective fence.” However, the parallelism is tighter if one derives the form from שָׂגָא/שָׂגָה (saga’/sagah, “to grow”); see J. N. Oswalt, Isaiah (NICOT), 1:351, n. 4. For this verb, see BDB 960 s.v. שָׂגָא.
