By the seventh month the people of Israel were all settled in their towns. Then they all assembled in Jerusalem,
and Joshua son of Jehozadak, his fellow priests, and Zerubbabel son of Shealtiel, together with his relatives, rebuilt the altar of the God of Israel, so that they could burn sacrifices on it according to the instructions written in the Law of Moses, the man of God. 1
Even though the returning exiles were afraid of the people who were living in the land, they rebuilt the altar where it had stood before. Then they began once again to burn on it the regular morning and evening sacrifices. 2
They celebrated the Festival of Shelters according to the regulations; each day they offered the sacrifices required for that day; 3
and in addition they offered the regular sacrifices to be burned whole and those to be offered at the New Moon Festival and at all the other regular assemblies at which the Lord is worshiped, as well as all the offerings that were given to the Lord voluntarily. 4

All the Levites twenty years of age or older were put in charge of the work of rebuilding the Temple.

They sang the Lord's praises, repeating the refrain: 6 "The Lord is good, and his love for Israel is eternal." Everyone shouted with all their might, praising the Lord, because the work on the foundation of the Temple had been started.
