21 "You shall not eat anything that dies of itself; you may give it to the alien who is within your towns, that he may eat it, or you may sell it to a foreigner; for you are a people holy to YHVH, your god, "You shall not boil a kid in its mother's milk.
The body is the temple of the indwelling soul. It is holy and should not be defiled. This admonition is even more important for the inner aspects of the temple; that which pertains to the thoughts and emotions. These should not be allowed to disfigure the sacred temple. The information regarding diet indicates the importance of how we care for this holy temple.
22 "You shall tithe all the yield of your seed, which comes forth from the field year by year.
23 And before YHVH, your god, in the place which he will choose, to make his name dwell there, you shall eat the tithe of your grain, of your wine, and of your oil, and the firstlings of your herd and flock; that you may learn to fear YHVH, your god, always.
24 And if the way is too long for you, so that you are not able to bring the tithe, when YHVH, your god, blesses you, because the place is too far from you, which YHVH, your god, chooses, to set his name there,
25 then you shall turn it into money, and bind up the money in your hand, and go to the place which YHVH, your god, chooses,
26 and spend the money for whatever you desire, oxen, or sheep, or wine or strong drink, whatever your appetite craves; and you shall eat there before YHVH, your god, and rejoice, you and your household.
27 And you shall not forsake the Levite who is within your towns, for he has no portion or inheritance with you.
28 "At the end of every three years you shall bring forth all the tithe of your produce in the same year, and lay it up within your towns;
29 and the Levite, because he has no portion or inheritance with you, and the sojourner, the fatherless, and the widow, who are within your towns, shall come and eat and be filled; that YHVH, your god, may bless you in all the work of your hands that you do.
The restating of the Law of Tithing (the giving of 10%) is emphasizing its importance. The 10th part symbolizes the Spirit in manifestation. The One is the one Source of all. The zero is the circle which completes itself by returning to its starting point. And so, ten, symbolizes God manifest in his creation and yet, all is One.
