Well to tithe biblically you wouldn't ever use money any tithe given in the Old Testament was a Grain offering or Animal offering.
And to be more specific there were actually Four different kinds of Tithe in the Old Testament. In the quotes is from an author who has studied this very extensively and is basically his life's work. I posted earlier but this guy explains it all so much better.
"(1) The first religious tithe, called the Levitical tithe, had two parts. Again, the whole first tithe was given to the Levites who were only servants to the priests (Num 18:21-24; Neh 10:37b). The Levites, in turn, gave one tenth of the whole tithe to the priests (Num 18:25-28; Neh 10:38). (2) According to Deuteronomy 12 and 14, the second religious tithe, called the feast tithe, was eaten by worshipers in the streets of Jerusalem during the three yearly festivals (Deu 12:1-19; 14:22-26). (3) And, according to Deuteronomy 14 and 26, a third tithe, called the poor tithe, was kept in the towns every third year to feed the poor (Deu 14:28, 29; 26:12, 13). (4) Also, according to First Samuel 8:14-17, the ruler collected the first and best ten per cent for political use. During Jesus’ time Rome collected the first ten per cent (10%) of most food and twenty per cent (20%) of fruit crops as its spoils of war. It is dishonest to single out the one religious tithe and ignore the other two important religious tithes."
Notice this, the priest would never use the tithe for building, the Tent of Meeting was built through free will offerings from the people and the Temple in Jerusalem was built by Highly Taxing the people into rebellion.
We have seen in our day a large distortion of biblical tithing in that many will twist the arms of the congregation in order to get "God's 10% cut" True prosperity and joy comes from a Thankful and Happy heart that graciously and mercifully gives to those that truly need the help. I hope this helps!
God Bless,
Matthew
