I give to the Levites all the tithes in Israel as their inheritance in return for the work they do while serving at the tent of meeting

 Numbers 17-19

So Moses spoke to the Israelites, and their leaders gave him twelve staffs, one for the leader of each of their ancestral tribes, and Aaron’s staff was among them. Moses placed the staffs before the Lord in the tent of the covenant law. The next day Moses entered the tent and saw that Aaron’s staff, which represented the tribe of Levi, had not only sprouted but had budded, blossomed and produced almonds.

The Lord said to Aaron, “You, your sons and your family are to bear the responsibility for offenses connected with the sanctuary, and you and your sons alone are to bear the responsibility for offenses connected with the priesthood. Bring your fellow Levites from your ancestral tribe to join you and assist you when you and your sons minister before the tent of the covenant law. They are to be responsible to you and are to perform all the duties of the tent, but they must not go near the furnishings of the sanctuary or the altar. Otherwise both they and you will die. They are to join you and be responsible for the care of the tent of meeting—all the work at the tent—and no one else may come near where you are.

Then the Lord said to Aaron, “I myself have put you in charge of the offerings presented to me; all the holy offerings the Israelites give me I give to you and your sons as your portion, your perpetual share. You are to have the part of the most holy offerings that is kept from the fire. From all the gifts they bring me as most holy offerings, whether grain or sin[a] or guilt offerings, that part belongs to you and your sons. Eat it as something most holy; every male shall eat it. You must regard it as holy.

The Lord said to Aaron, “You will have no inheritance in their land, nor will you have any share among them; I am your share and your inheritance among the Israelites.

I give to the Levites all the tithes in Israel as their inheritance in return for the work they do while serving at the tent of meeting.

Why?

The staff of Armon was not only sprouting but had budded, blossomed, and produced almonds. It is out of nature's rule for almonds, so it symbolize it is the work of the Lord and God's chosen in on Armon tribe.

The Lord said to Moses, “Put back Aaron’s staff in front of the ark of the covenant law, to be kept as a sign to the rebellious. This will put an end to their grumbling against me, so that they will not die.” Moses did just as the Lord commanded him.

How?

The tithes in Chriatisns are belong to the Lord, so we give tithes today to honor the Lord and represent out devoteion and thanks giving from our Lord. I am glad that I have this a little opportunity to serve the Lord. All I have is the grace of the Lord!
