The priests ate them and shared them. The church has changed the meaning. In the days of Christ the church was a refuge. It was not a place to come sing, but a place to hear God's word and understand if we're on the right track, and to have a refuge, a place to stay for widows and orphans. The sacrifice that people came and brought was shared all together.
Tithes are different.
See, in our church we say, if you can't afford the church tithe then just give a pledge. The pledges worked real well. For the first fiscal year we were out of debt, paid everything. Nobody knows what everyone else pledged. Only the bookkeeper knows everything.
