14:27 ^a Because the Levites had no geographic inheritance of their own and were forbidden to engage in secular work, they depended on the support of other tribes (see 12:12 ^b).
14:28 ^c An annual tithe was required of all adult Israelite males as part of their festival observances (15:20 ^d; 16:16-17 ^e). The tithe every third year met the needs of the Levites and other dependent classes in Israelite society (14:29 ^f). See study note on Lev 27:30.

Thematic note: Clean, Unclean, and Holy
The rites and regulations establishing cleanness and uncleanness were to distinguish Israel from the surrounding nations. To understand a rationale behind these regulations, one suggestion has been that unclean things are associated with death or the ground (see, e.g., Lev 21:1 ^g, 11 ^h; 22:8 ⁱ). Recent studies, however, suggest the principle of “normalcy.” God is a God of order. Things that are normal in God’s order are called “clean” and are “permitted.” Abnormal things would be unfit for food or offerings and would be “unclean.” A normal land animal would be a vegetarian (see Gen 1:30 ^j). A normal human body would have no infections or discharges. A normal piece of cloth would have no mildew on it. If abnormalities occurred, the animal, person, or cloth was unclean.
What is unclean is not sinful but represents a kind of unworthiness that cannot come in contact with what is holy (e.g., Lev 11:44-45 ^k). If it is cleansed, it acquires the potential for holiness; it may be dedicated to God and become holy. If what is holy (such as the Sabbath) is treated like something common, God is blasphemed and the thing is profaned. If what is clean becomes unclean, it is defiled and requires cleansing. Some things, such as unclean animals, fish, or birds, remain unclean by definition and can never be cleansed, and, thus, can never become holy.
In the new covenant, things that were previously unclean have been declared clean (Acts 10:15 ^l, 28 ^m, 45 ⁿ). Yet God is still a God of order (1 Cor 14:33 ^o) and wants worship to be conducted in an orderly way (1 Cor 14:40 ^p). While God’s grace is abundant to repentant sinners, some things are still repulsive to his holiness and should never be brought into his presence (e.g., Ananias and Sapphira’s offering; see Acts 5:1-11 ^q).
