"On the fourth day, in the house of our God, we weighed out the silver and gold and the sacred articles into the hands of Meremoth son of Uriah, the priest. Eleazer son of Phinehas was with him, and so were the Levites Jozabad son of Jeshua and Noadiah son of Binnui. Everything was accounted for by number and weight, and the entire weight was recorded at that time." NIV translation
After their rest, they delivered the treasures to the temple and we notice that it was all there and handed over to the priest. In this we see that God completely protects as not a single piece was lost during the trip. We also see that those entrusted with it did not keep any for themselves but instead handed it all over for the service of the Lord. There are many who are entrusted with offerings for the work of God but somehow it doesn't all end up being delivered. We must remember that this is in fact robbing God and His work.
"Then the exiles who had returned from captivity sacrificed burnt offerings to the God of Israel: twelve bulls for all Israel, ninety-six rams, seventy-seven male lambs and, as a sin offering, twelve male goats. All this was a burnt offering to the Lord. They also delivered the king's orders to the royal satraps and to the governors of Trans-Euphrates, who then gave assistance to the people and to the house of God." NIV translation
The entire assembly then presented the sacrifices to God for their sins. The king's orders were passed on to the government leaders and they obeyed by assisting in the provision for the temple.
