Compared with the dedication of the first temple this one was very modest. Solomon had offered more than 200 times as many animals.96
The Jews offered one sin offering, which involved slaying a goat, for each of the 12 tribes (v. 17). The reference to the number of Israel's tribes being 12 shows that none of the tribes were "lost"during the captivity, as some modern cults claim. The people still considered the nation to be a confederation of 12 tribes, and they called it "Israel"(2:2, 59).
"The remnant who had returned make solemn confession of sin in the name of the whole scattered and dispersed race. They acknowledge the essential unity of Israel's tribes alike in the consequences of sin, in the possibilities of restoration, and in the renewed consecration to God's service."97
The Passover celebration took place five weeks after the temple dedication. The Feast of Unleavened Bread began on the day after Passover and lasted seven days (Lev. 23:6-8). Note that some Gentile converts had evidently accompanied the remnant from Babylon to Jerusalem (v. 21).
The reference to Darius (cf. vv. 6-12) as the "king of Assyria"(v. 22) is unusual but not unique. In some ancient Near Eastern king lists the rulers of territories that were previously independent are referred to as kings of those countries.98
"Perhaps, however, it is meant to awaken memories of the traditional oppressor (cf. Ne. 9:32), whose empire first Babylon and then Persia had inherited, but whose policies were now dramatically reversed."99
Naturally the restoration Jews rejoiced greatly that their national worship of Yahweh could continue again as the Mosaic Covenant specified. Since life in Israel rested on the worship of Yahweh, the re-establishment of life under the Mosaic Law depended on the re-establishment of Mosaic worship. Thus the record of the completion of the temple and the resumption of worship is the climax of this first part of Ezra (chs. 1-6).
