Numbers 18:21

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 at that time were some appointed over the chambers for the treasures, for the offerings, for the firstfruits, and for the tithes, to gather into them out of the fields of the cities the portions of the law for the priests and Levites: for Judah rejoiced for the priests and for the Levites that waited.

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.

Thou shalt truly tithe all the increase of thy seed, that the field bringeth forth year by year. And thou shalt eat before the Lord thy God, in the place which he shall choose to place his name there, the tithe of thy corn, of thy wine, and of thine oil, and the firstlings of thy herds and of thy flocks; that thou mayest learn to fear the Lord thy God always. And if the way be too long for thee, so that thou art not able to carry it; or if the place be too far from thee, which the Lord thy God shall choose to set his name there, when the Lord thy God hath blessed thee: Then shalt thou turn it into money, and bind up the money in thine hand, and shalt go unto the place which the Lord thy God shall choose: And thou shalt bestow that money for whatsoever thy soul lusteth after, for oxen, or for sheep, or for wine, or for strong drink, or for whatsoever thy soul desireth: and thou shalt eat there before the Lord thy God, and thou shalt rejoice, thou, and thine household, 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 verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:

They clave to their brethren, their nobles, and entered into a curse, and into an oath, to walk in God’s law, which was given by Moses the servant of God, and to observe and do all the commandments of the Lord our Lord, and his judgments and his statutes;

Then brought all Judah the tithe of the corn and the new wine and the oil unto the treasuries.

And I, behold, I have taken your brethren the Levites from among the children of Israel: to you they are given as a gift for the Lord, to do the service of the tabernacle of the congregation.

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.

Thou mayest not eat within thy gates the tithe of thy corn, or of thy wine, or of thy oil, or the firstlings of thy herds or of thy flock, nor any of thy vows which thou vowest, nor thy freewill offerings, or heave offering of thine hand: But thou must eat them before the Lord thy God in the place which the Lord thy God shall choose, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates: and thou shalt rejoice before the Lord thy God in all that thou puttest thine hands unto. Take heed to thyself that thou forsake not the Levite as long as thou livest upon the earth.

And blessed be the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all.

And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is the Lord’s: it is holy unto the Lord. And if a man will at all redeem ought of his tithes, he shall add thereto the fifth part thereof. And concerning the tithe of the herd, or of the flock, even of whatsoever passeth under the rod, the tenth shall be holy unto the Lord. He shall not search whether it be good or bad, neither shall he change it: and if he change it at all, then both it and the change thereof shall be holy; it shall not be redeemed.

But the tithes of the children of Israel, which they offer as an heave offering unto the Lord, I have given to the Levites to inherit: therefore I have said unto them, Among the children of Israel they shall have no inheritance. And the Lord spake unto Moses, saying, Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the Lord, even a tenth part of the tithe.

And they shall keep his charge, and the charge of the whole congregation before the tabernacle of the congregation, to do the service of the tabernacle. And they shall keep all the instruments of the tabernacle of the congregation, and the charge of the children of Israel, to do the service of the tabernacle.

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.

Let him that is taught in the word communicate unto him that teacheth in all good things.
