1 Heb “In the seventh [month], on the twenty-first day of the month.” 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).
2 Heb “the word of the Lord came by the hand of Haggai the prophet, saying.” The has בְּיַד (béyad, “by the hand of” = “through” [so , , ] as in 1:1, 3); the Murabba’at Dead Sea text reads אֶל (’el, “to”), perhaps because the following command is given to the prophet.
