Ezra 3:6

From the first of the seventh month began they to offer
burnt offerings unto the Lord
And which day was not only a new moon, but a grand festival, the feast of blowing of trumpets, ( Leviticus 23:24 Leviticus 23:25 ) , and no doubt but they observed the tenth day of this month, with all the rites of it, which was the day of atonement, ( Leviticus 23:27-32 ) ,

but the foundation of the temple of the Lord was not yet laid;
they began first with sacrifices, that having thereby given thanks to God for their return to their own land, and for all the benefits they enjoyed, and made atonement for their sins in a typical way, they might be the more prepared and fit for the work of building the temple; or, "though the foundation" of it was not laid ^F26, yet they offered the above sacrifices.
