Haggai 2:1 New English Translation

2 On the twenty-first day of the seventh month,^[a] the Lord’s message came through^[b] the prophet Haggai again:

Haggai 2:1 tn Heb “In the seventh [month], on the twenty-first day of the month.”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).
Haggai 2:1 tc The MT has בְּיַד (b^eyad, “by the hand of” = “through” [so NAB, NIV, NLT] as in 1:1, 3); the Murabba’at Dead Sea text reads אֶל (ʾel, “to”), perhaps because the following command is given to the prophet.
