Thematic Bible: The amount to be tithed

And Jacob vowed a vow, saying, If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on, so that I come again to my father's house in peace, and Jehovah will be my God, then this stone, which I have set up for a pillar, shall be God's house. And of all that thou shalt give me I will surely give the tenth unto thee.

And Jehovah said unto Aaron, Thou shalt have no inheritance in their land, neither shalt thou have any portion among them: I am thy portion and thine inheritance among the children of Israel. And unto the children of Levi, behold, I have given all the tithe in Israel for an inheritance, in return for their service which they serve, even the service of the tent of meeting.
