How Should Christians pay tithe?

Deuteronomy 14:25 – Then shalt thou turn it into money, and bind up the money in thine hand, and shalt go unto the place which the LORD thy God shall choose:

1.       In the Old Testament, the Israelites pay tithes from the increase of their crops, because they were mainly farmers

2.       In the contemporary world, Christians should monetize their tithes in line with the Scriptures quoted above.
