No one takes this honor upon himself; he must be called by God, just as Aaron was.

“Next, have your brother Aaron brought to you from among the Israelites, along with his sons Nadab, Abihu, Eleazar, and Ithamar, to serve Me as priests.

He has brought you near, you and all your fellow Levites, but you are seeking the priesthood as well. Therefore, it is you and all your followers who have conspired against the LORD! As for Aaron, who is he that you should grumble against him?”

and write Aaron’s name on the staff of Levi, because there must be one staff for the head of each tribe. Place the staffs in the Tent of Meeting in front of the Testimony, where I meet with you. The staff belonging to the man I choose will sprout, and I will rid Myself of the constant grumbling of the Israelites against you.” So Moses spoke to the Israelites, and each of their leaders gave him a staff—one for each of the leaders of their tribes, twelve staffs in all. And Aaron’s staff was among them. Then Moses placed the staffs before the LORD in the Tent of the Testimony. The next day Moses entered the Tent of the Testimony and saw that Aaron’s staff, representing the house of Levi, had sprouted, put forth buds, blossomed, and produced almonds. Then Moses brought out all the staffs from the LORD’s presence to all the Israelites. They saw them, and each man took his own staff. The LORD said to Moses, “Put Aaron’s staff back in front of the Testimony, to be kept as a sign for the rebellious, so that you may put an end to their grumbling against Me, lest they die.”

But only you and your sons shall attend to your priesthood for everything concerning the altar and what is inside the veil, and you are to perform that service. I am giving you the work of the priesthood as a gift, but any outsider who comes near the sanctuary must be put to death.” ... Behold, I have given to the Levites all the tithes in Israel as an inheritance in return for the work they do, the service of the Tent of Meeting. No longer may the Israelites come near to the Tent of Meeting, or they will incur guilt and die. The Levites are to perform the work of the Tent of Meeting, and they must bear their iniquity. This is a permanent statute for the generations to come. The Levites will not receive an inheritance among the Israelites. For I have given to the Levites as their inheritance the tithe that the Israelites present to the LORD as a contribution. That is why I told them that they would not receive an inheritance among the Israelites.” And the LORD instructed Moses, “Speak to the Levites and tell them: ‘When you receive from the Israelites the tithe that I have given you as your inheritance, you must present part of it as an offering to the LORD—a tithe of the tithe.

Thus any tithe from the land, whether from the seed of the land or the fruit of the trees, belongs to the LORD; it is holy to the LORD. If a man wishes to redeem part of his tithe, he must add a fifth to its value. Every tenth animal from the herd or flock that passes under the shepherd’s rod will be holy to the LORD. He must not inspect whether it is good or bad, and he shall not make any substitution. But if he does make a substitution, both the animal and its substitute shall become holy; they cannot be redeemed.’”

“Speak to the Levites and tell them: ‘When you receive from the Israelites the tithe that I have given you as your inheritance, you must present part of it as an offering to the LORD—a tithe of the tithe. Your offering will be reckoned to you as grain from the threshing floor or juice from the winepress. So you are to present an offering to the LORD from all the tithes you receive from the Israelites, and from these you are to give the LORD’s offering to Aaron the priest. You must present the offering due the LORD from all the best of every gift, the holiest part of it.’ Therefore say to the Levites, ‘When you have presented the best part, it will be reckoned to you as the produce of the threshing floor or winepress. And you and your households may eat the rest of it anywhere; it is the compensation for your work at the Tent of Meeting. Once you have presented the best part of it, you will not incur guilt because of it. But you must not defile the sacred offerings of the Israelites, or else you will die.’”

Moreover, he commanded the people living in Jerusalem to make a contribution for the priests and Levites so that they could devote themselves to the Law of the LORD. As soon as the order went out, the Israelites generously provided the firstfruits of the grain, new wine, oil, and honey, and of all the produce of the field, and they brought in an abundance—a tithe of everything. And the Israelites and Judahites who lived in the cities of Judah also brought a tithe of their herds and flocks and a tithe of the holy things consecrated to the LORD their God, and they laid them in large heaps.

I also learned that because the portions for the Levites had not been given to them, all the Levites and singers responsible for performing the service had gone back to their own fields.

For when Melchizedek met Abraham, Levi was still in the loin of his ancestor.

And God told him, “I am God Almighty. Be fruitful and multiply. A nation—even a company of nations—shall come from you, and kings shall descend from you.

All those belonging to Jacob who came to Egypt—his direct descendants, besides the wives of Jacob’s sons—numbered sixty-six persons.

The descendants of Jacob numbered seventy in all, including Joseph, who was already in Egypt.

Nevertheless, you are not the one to build it; but your son, your own offspring, will build the house for My Name.’
