From Genesis to Revelation, tithing is the only financial system God endorses. He shows that blessings accrue to those who faithfully tithe of the increase He has bestowed upon them. Tithing, in its simplest form, is returning one-tenth of one's income to God for His use. Jacob must have been taught about tithing by his grandfather, Abraham, and his father, Isaac. The tithe goes to God through His representative, the priest, and it is consistently one-tenth. This law was in effect long before it was commanded through Moses. Abram, blessed for his faithfulness to God, gave tithes in recognition of God's rulership and providence.

Abraham's example of tithing, as seen in Genesis 14:18-20, demonstrates that tithing is not limited to agricultural produce. He gave ten percent of the spoils of war, which included gold, silver, apparel, and other valuable items, to God, showing that tithing applies to the work of one's hand beyond farming. This instance highlights that tithing encompasses non-agricultural endeavors, reinforcing the principle that God's requirement of a tenth extends to all forms of increase. Similarly, Jacob's promise in Genesis 28:20-22 to give a tenth to God for protection, food, and raiment during his travels further illustrates that tithing was understood and practiced outside the context of agriculture, likely passed down from Abraham through Isaac to Jacob.
