Deuteronomy 12:19

And the Levite that is within thy gates; thou shalt not forsake him; for he hath no part nor inheritance with thee. At the end of three years thou shalt bring forth all the tithe of thine increase the same year, and shalt lay it up within thy gates: And the Levite, (because he hath no part nor inheritance with thee,) and the stranger, and the fatherless, and the widow, which are within thy gates, shall come, and shall eat and be satisfied; that the LORD thy God may bless thee in all the work of thine hand which thou doest.

And the priests and the Levites that were in all Israel resorted to him out of all their coasts.

Moreover he commanded the people that dwelt in Jerusalem to give the portion of the priests and the Levites, that they might be encouraged in the law of the LORD. And as soon as the commandment came abroad, the children of Israel brought in abundance the firstfruits of corn, wine, and oil, and honey, and of all the increase of the field; and the tithe of all things brought they in abundantly. And concerning the children of Israel and Judah, that dwelt in the cities of Judah, they also brought in the tithe of oxen and sheep, and the tithe of holy things which were consecrated unto the LORD their God, and laid them by heaps. In the third month they began to lay the foundation of the heaps, and finished them in the seventh month. And when Hezekiah and the princes came and saw the heaps, they blessed the LORD, and his people Israel. Then Hezekiah questioned with the priests and the Levites concerning the heaps. And Azariah the chief priest of the house of Zadok answered him, and said, Since the people began to bring the offerings into the house of the LORD, we have had enough to eat, and have left plenty: for the LORD hath blessed his people; and that which is left is this great store. Then Hezekiah commanded to prepare chambers in the house of the LORD; and they prepared them, And brought in the offerings and the tithes and the dedicated things faithfully: over which Cononiah the Levite was ruler, and Shimei his brother was the next. And Jehiel, and Azaziah, and Nahath, and Asahel, and Jerimoth, and Jozabad, and Eliel, and Ismachiah, and Mahath, and Benaiah, were overseers under the hand of Cononiah and Shimei his brother, at the commandment of Hezekiah the king, and Azariah the ruler of the house of God. And Kore the son of Imnah the Levite, the porter toward the east, was over the freewill offerings of God, to distribute the oblations of the LORD, and the most holy things. And next him were Eden, and Miniamin, and Jeshua, and Shemaiah, Amariah, and Shecaniah, in the cities of the priests, in their set office, to give to their brethren by courses, as well to the great as to the small: Beside their genealogy of males, from three years old and upward, even unto every one that entereth into the house of the LORD, his daily portion for their service in their charges according to their courses; Both to the genealogy of the priests by the house of their fathers, and the Levites from twenty years old and upward, in their charges by their courses; And to the genealogy of all their little ones, their wives, and their sons, and their daughters, through all the congregation: for in their set office they sanctified themselves in holiness: Also of the sons of Aaron the priests, which were in the fields of the suburbs of their cities, in every several city, the men that were expressed by name, to give portions to all the males among the priests, and to all that were reckoned by genealogies among the Levites. And thus did Hezekiah throughout all Judah, and wrought that which was good and right and truth before the LORD his God. And in every work that he began in the service of the house of God, and in the law, and in the commandments, to seek his God, he did it with all his heart, and prospered.

And we cast the lots among the priests, the Levites, and the people, for the wood offering, to bring it into the house of our God, after the houses of our fathers, at times appointed year by year, to burn upon the altar of the LORD our God, as it is written in the law: And to bring the firstfruits of our ground, and the firstfruits of all fruit of all trees, year by year, unto the house of the LORD: Also the firstborn of our sons, and of our cattle, as it is written in the law, and the firstlings of our herds and of our flocks, to bring to the house of our God, unto the priests that minister in the house of our God: And that we should bring the firstfruits of our dough, and our offerings, and the fruit of all manner of trees, of wine and of oil, unto the priests, to the chambers of the house of our God; and the tithes of our ground unto the Levites, that the same Levites might have the tithes in all the cities of our tillage. And the priest the son of Aaron shall be with the Levites, when the Levites take tithes: and the Levites shall bring up the tithe of the tithes unto the house of our God, to the chambers, into the treasure house. For the children of Israel and the children of Levi shall bring the offering of the corn, of the new wine, and the oil, unto the chambers, where are the vessels of the sanctuary, and the priests that minister, and the porters, and the singers: and we will not forsake the house of our God.

Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things? If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ. Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar? Even so hath the Lord ordained that they which preach the gospel should live of the gospel.
