These are the inheritances which the children of Israel took in the land of Canaan, which Eleazar the priest, Joshua the son of Nun, and the heads of the fathers’ houses of the tribes of the children of Israel, distributed to them, by the lot of their inheritance, as Yahweh commanded by Moses, for the nine tribes, and for the half-tribe. For Moses had given the inheritance of the two tribes and the half-tribe beyond the Jordan; but to the Levites he gave no inheritance among them. (Joshua 14:1-4)
As you'd be told if you kept reading till Chapter 18, this was because the Levites' duties as priests, their access to Yahweh Himself, were the inheritances they were meant to enjoy and delight themselves in. What an important reminder for us! Whether you read these words as one with great earthly wealth or as someone struggling to get by, your only real inheritance – the place from which you should derive all your identity and joy – is your access to Jesus and, by Him, His Father. Everything else is as nothing. His love - and the service of that love - is everything.
"But you are God’s 'chosen generation,' his 'royal priesthood,' his 'holy nation,' his 'peculiar people' — all the old titles of God’s people now belong to you..." 1 Peter 2
