‘ These are the inheritances which Eleazar the priest, and Joshua the son of Nun, and the heads of the fathers of the tribes of the children of Israel, distributed for inheritance by lot in Shiloh before YHWH, at the door of the Tent of Meeting. So they made an end of dividing the land.'
This summarises Joshua 18:1 to Joshua 19:51 (see Joshua 14:1; Joshua 18:1). Eleazar was ‘the Priest' at the central sanctuary, here called the Tent of Meeting, who was responsible for the use of Urim and Thummim and for casting lots before YHWH. Joshua was the Servant of Yahweh, successor to the great Moses. The heads of the fathers of the tribes of the children of Israel were princes from each tribe appointed for this service, whose names are given in Numbers 34:18-29. It was their responsibility to arrange the distribution of the inheritances of the tribes.
This distribution took place before YHWH by lot at the door of the Tent of Meeting (the Tabernacle), beyond which the princes could not go, and which was now sited at Shiloh, see Joshua 18:1. Previously it had been at Gilgal (Joshua 14:2 with Joshua 14:6).
