In regard to property, they were required to give one tenth of all their yearly income, to support the Levites, the priests, and the religious service. Next, they were required to give the first fruits of all their corn, wine, oil, and fruits, and the first-born of all their cattle, for the Lord's treasury, to be employed for the priests, the widow, the fatherless, and the stranger. The first-born, also, of their children, were the Lord's, and were to be redeemed by a specified sum, paid into the sacred treasury. Besides this, they were required to bring a freewill offering to God, every time they went up to the three great yearly festivals. In addition to this, regular yearly sacrifices, of cattle and fowls, were required of each family, and occasional sacrifices for certain sins or ceremonial impurities. In reaping their fields, they were required to leave unreaped, for the poor, the corners; not to glean their fields, olive-yards, or vineyards; and, if a sheaf was left, by mistake, they were not to return for it, but leave it for the poor. When a man sent away a servant, he was thus charged: "Furnish him liberally out of thy flock, and out of thy floor, and out of thy wine-press." When a poor man came to borrow money, they were forbidden to deny him, or to take any interest; and if, at the sabbatical, or seventh, year, he could not pay, the debt was to be cancelled. And to this command, is added the significant caution, "Beware that there be not a thought in thy wicked heart, saying, the seventh year, the year of release, is at hand; and thine eye be evil against thy poor brother, and thou givest him nought; and he cry unto the Lord against thee, and it be sin unto thee. Thou shalt surely give him," "because that for this thing the Lord thy God shall bless thee in all thy works, and in all that thou puttest thine hand unto." Besides this, the Levites were distributed through the land, with the intention that they should be instructors and priests in every part of the nation. Thus, one twelfth of the people were set apart, having no landed property, to be priests and teachers; and the other tribes were required to support them liberally.
