Tithing is first introduced in Genesis 4:4 and continues right on through to the New Testament. (Matthew 23:23) It is not an Old Testament law, (Matthew 5:17-19) but it is an continued teaching throughout the Bible.

And they exceeded our expectations: They gave themselves first of all to the Lord, and then by the will of God also to us.
