In Numbers and Deuteronomy it talks about the inheritance of the Levites, of the priests. While the other tribes of Jacob were given land as an inheritance, the Levites were given none of the sort but it says, "The Lord is his inheritance." (Deuteronomy 10:9)
Now Jesus comes and takes His place as our High Priest (Hebrews 2:17, 3:1, 4:14-15, 5:1-10, 6:20, 7:27-28, 8:1,3, 9:11, 9:25, 13:11-12) calling us into His royal priesthood (1Peter 2:9) to become co-heirs with Christ and partake of His portion- Himself (Romans 8:17). Now the Lord is our inheritance also.
That's such a simple statement with profound and exquisite consequences. He came to establish an inheritance that we could share in!
Back in Numbers and Deuteronomy, the Lord takes time going into great detail describing the portions that were to be allotted to the Levites. He provided completely for them, they had no need. Nor do we who call ourselves His. What an inheritance.
