Building Materials
6 From the first day of the seventh month they began to offer burnt offerings to the Lord. But the foundation of the temple of the Lord was not yet laid. 7 So they gave money to the masons and the carpenters, and food, drink, and oil to the Sidonians and the Tyrians to bring cedar trees from Lebanon to the sea, to Joppa, according to the grant that they had from Cyrus king of Persia.
Ezra 3:6-7 NLT
These verses describe when the Israelites began to rebuild the temple, and how money and goods were exchanged for building materials. God uses our giving to fulfill His purposes.
