'Thereof' in the Bible

In the first year of Cyrus the king, Cyrus the king made a decree: Concerning the house of God at Jerusalem, let the house be builded, the place where they offer sacrifices, and let the foundations thereof be strongly laid; the height thereof threescore cubits, and the breadth thereof threescore cubits;

For we are bondmen; yet our God hath not forsaken us in our bondage, but hath extended lovingkindness unto us in the sight of the kings of Persia, to give us a reviving, to set up the house of our God, and to repair the ruins thereof, and to give us a wall in Judah and in Jerusalem.

Let now our princes be appointed for all the assembly, and let all them that are in our cities that have married foreign women come at appointed times, and with them the elders of every city, and the judges thereof, until the fierce wrath of our God be turned from us, until this matter be despatched.
