Numbers 18:19 YLT

¹⁷  'Only, the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou dost not ransom, holy they 'are': their blood thou dost sprinkle on the altar, and of their fat thou makest perfume, a fire-offering of sweet fragrance to Jehovah,

¹⁸  and their flesh is thine, as the breast of the wave-offering, and as the right leg, it is thine;

¹⁹  all the heave-offerings of the holy things which the sons of Israel lift up to Jehovah I have given to thee and to thy sons, and to thy daughters with thee, by a statute age-during, a covenant of salt, age-during it 'is' before Jehovah, to thee and to thy seed with thee.'

²⁰  And Jehovah saith unto Aaron, 'In their land thou dost not inherit, and a portion thou hast not in their midst: I 'am' thy portion, and thine inheritance in the midst of the sons of Israel;

²¹  and to the sons of Levi, lo, I have given all the tenth in Israel for inheritance in exchange for their service which they are serving -- the service of the tent of meeting.
