There are different kinds of giving in the Bible. The tithe was a tenth of one’s income (for the Old Testament Israelite, this typically came from the harvest yielded from land God had given them). The tithe was a regularly recurring gift that provided for the general service of the temple. Offerings were ways to worship God, above and beyond the tithe, to express devotion and thanksgiving when moved in the spirit or when there were particular needs, such as Israel had at the building of the Tabernacle in Exodus 35. As such, offerings were occasion driven.
