What the Bible says about Tithe as Financial Support for Ministry
(From Forerunner Commentary)
The principle of supporting the ministers of God's Work is in force in the New Testament church. Paul refers to the Old Testament law as his authority for taking tithes to preach the gospel. This, combined with Jesus' comments, shows a clear, New Testament application of the tithing law.
