2 They will have no inheritance in the midst of their fellow Israelites; the Lord alone is their inheritance, just as he had told them. 3 This shall be the priests’ fair allotment from the people who offer sacrifices, whether bull or sheep—they must give to the priest the shoulder, the jowls, and the stomach. 4 You must give them the best of your grain, new wine, and olive oil, as well as the best of your wool when you shear your flocks. 5 For the Lord your God has chosen them and their sons from all your tribes to stand and serve in his name permanently. 6 Suppose a Levite comes by his own free will from one of your villages, from any part of Israel where he is living, to the place the Lord chooses
5 All my kindred and our ancestral house of Naphtali sacrificed to the calf c that King Jeroboam of Israel had erected in Dan and on all the mountains of Galilee. 6 But I alone went often to Jerusalem for the festivals, as it is prescribed for all Israel by an everlasting decree. I would hurry off to Jerusalem with the first fruits of the crops and the firstlings of the flock, the tithes of the cattle, and the first shearings of the sheep. 7 I would give these to the priests, the sons of Aaron, at the altar; likewise the tenth of the grain, wine, olive oil, pomegranates, figs, and the rest of the fruits to the sons of Levi who ministered at Jerusalem. Also for six years I would save up a second tenth in money and go and distribute it in Jerusalem. 8 A third tenth I would give to the orphans and widows and to the converts who had attached themselves to Israel. I would bring it and give it to them in the third year, and we would eat it according to the ordinance decreed concerning it in the law of Moses and according to the instructions of Deborah, the mother of my father Tobiel, for my father had died and left me an orphan. 9 When I became a man I married a woman, a member of our own family, and by her I became the father of a son whom I named Tobias.
Notes and References
"... Altogether, Tobit's particular dependence on the Torah may be best summarised in the chart on the next page. As we have already indicated, everything Tobit offers has a general basis in the Pentateuch. The idea that offerings should be a part of pilgrimages is found in Deuteronomy 16. Specific offerings are described in Deuteronomy 8, 14, and 26; Numbers 18; and Leviticus 27. Whenever possible, Tobit follows Numbers 18, supplementing it with other sources only after it has been exhausted. This, too, appears to be part of a general trend. All in all, the Book of Tobit stands out by virtues of its exhaustive detail, combining tithes and first fruits of almost every kind in rapid succession. This has been acknowledged by many scholars who are simply studying tithing or Jewish law in Second Temple times. This is so much the case that it is worth considering whether Tobit's tithing system corresponded with one that was actually ever practised or whether it is in part a literary construction ..."
