God's kingdom in this world; Tithe

Numbers 18:1-32
Responsible for the care of
Service of the priesthood as a gift.
Said to Aaron:
Offerings from the Israelites the Lord gives to them as their portion and regular share.
Redeem the firstborn son and male of unclean animals. But you must not redeem the firstborn of an ox, a sheep or a goat; they are holy. Their meat is to be yours.
Have not inheritance in their land, not will you have a share among them; I am your share and your inheritance among the Israelites.
Said to Moses:
The tithe from Isrealite is given to Levites, you must presnt a tenth of the tithe as the Lord's offering. you must give the Lord's portion to Aaron the priest.
Present as the Lord's portion the best and holiest part of everthing given to you.
Redeem:

1. Compensate for the faults or bad aspects of (something): "a disappointing debate redeemed by an outstanding speech".
2. Do something that compensates for poor past performance or behavior.
3. to buy or pay off; clear by payment: to redeem a mortgage.
   2.

   to buy back, as after a tax sale or a mortgage foreclosure.
   3.

   to recover (something pledged or mortgaged) by payment or other satisfaction

Responsible: answerable or accountable, as for something within one's power, control,or management (often followed by to  or for  ): He is responsible to thepresident for his decisions.
Neither priests nor Levites share in the inheritance of the land: God is their share.
God gives the sacrificial offerings, firstfruits and firstlings. THe Levites are given the nation's tithes. They in turn give one-tenth to the priests, as thier gift to God. What they give must be the best.
Why?
Tithe is the gift to servant of the Lord, all we have are the blessing of the Lord, so we are responsible to servants of the Lord.
Give the best to the Lord for He is worthy for praise and worthy for honor.
The servants of the Lord have to be Holy and take responsibility to serve between the Lord and God's people.
The portion belongs to God cann't be redeem have to be burnt offering.
Priesthood is gift for it is chosen by the Lord. It is an honor and Holy work.
Aaron is the highest priest, Moses is the leader of Israelite, so the Lord makes clear what their parts are.
How?
Give tithe of our products is the regulation from the Lord and it is our responsibility to the Lord. Levites has not inhertance in the land. Both are enough for living and serving in everything. This is the kingdom of the Lord in the world.
