Tobit 1:6–8

6 But I alone went often to Jerusalem for the feasts, as it is ordained for all Israel by an everlasting decree. Taking the first fruits and the tithes of my produce and the first shearings, I would give these to the priests, the sons of Aaron, at the altar. 7 Of all my produce I would give a tenth to the sons of Levi who ministered at Jerusalem; a second tenth I would sell, and I would go and spend the proceeds each year at Jerusalem; 8 the third tenth I would give to those to whom it was my duty, as Deborah my father’s mother had commanded me, for I was left an orphan by my father.
