C. F. Keil and Franz Delitzsch on Ezra 3:1

The Altar of Burnt-Offering Erected, the Feast of Tabernacles Celebrated, and the Foundations of the Temple Laid - Ezr 3:1-13

On the approach of the seventh month, the people assembled in Jerusalem to restore the altar of burnt-offering and the sacrificial worship, and to keep the feast of tabernacles (Ezr 3:1-7); and in the second month of the following year the foundations of the new temple were laid with due solemnity (Ezr 3:8-13). Comp. 1 Esdr. 5:46-62.The building of the altar, the restoration of the daily sacrifice, and the celebration of the feast of tabernacles. -

Ezr 3:1 When the seventh month was come, and the children of Israel were in the cities, the people gathered themselves together as one man to Jerusalem. The year is not stated, but the year in which they returned from Babylon is intended, as appears from Ezr 3:8, which tells us that the foundations of the temple were laid in the second month of the second year of their return. The words, ”and the children of Israel were in the cities,” are a circumstantial clause referring to Ezr 2:70, and serving to elucidate what follows. From the cities, in which each had settled in his own (Ezr 2:1), the people came to Jerusalem as one man, i.e., not entirely (Bertheau), but unanimously (ὁμοθυμαδόν, 1 Esdr. 5:46); comp. Neh 8:1; Jdg 20:1.The more precise statement of 1 Esdr. 5:46, εἰς τὸ εὐρύχωρον τοῦ πρώτου πυλῶνος τοῦ πρὸς τῇ ἀνατολῇ, according to which Bertheau insists upon correcting the text of Ezra, is an arbitrary addition on the part of the author of this apocryphal book, and derived from Neh 8:1.
