In this passage, we see the system whereby rooms were made for the tithes, offerings, and firstfruits to be gathered in to the house of God. It states that this happened because “Judah rejoiced over the priests and Levites who ministered.” The singers and the gatekeepers kept the charge of their God and the charge of the purification, making sure that the temple was not desecrated. So, in the days of Nehemiah and Zerubbabel, the gatekeepers and singers had portions of provision, and the holy things were consecrated for the Levites, and the Levites consecrated them for the priests.
Today, people question the practice of tithing and giving, and some just ignore it, even in the church. However, there is a blessing in having spiritual leaders who dedicate themselves full-time to the work of the ministry. The church can rejoice over this ministry. However, this ministry does not happen without the faithfulness in giving described here in this passage. God is looking for people to supply the needs of the house of God and the ministers of God, and then the people can rejoice over the ministry. Is bivocational ministry valid? Of course it is. However, it should not be necessary because of the lack of support on the part of the people in the church. It is Biblical to tithe and give and support ministry. That is God’s plan.
