Tithing
Part of the Mosaic Law.
Leviticus 27:30-33
Deuteronomy 14:22,23
II Chronicles 31:5,6

1/10th of all the livestock, crops and spoils of war was given to the priests and kings.

Read the verses above to get the details.

The Mosaic Law was fulfilled with the death of Jesus, so the tithe is not binding in Christianity.
Hebrews 7:18,19

Christian giving is based on compassion and love, not the regulations of law.
