C. F. Keil and Franz Delitzsch on Joshua 19:51

Jos 19:51

Closing formula to the account of the distribution of the land, which refers primarily to Jos 18:1., as the expression “in Shiloh” shows, but which also includes Josh 14-17. The Preamble - Jos 1:1-9

After the death of Moses the Lord summoned Joshua, the servant of Moses, whom He had appointed as the leader of Israel into Canaan, to go with all the people across the Jordan, and take the land which had been promised to the fathers on oath, assuring him at the same time of His powerful aid, on condition that he observed the law of Moses faithfully. This summons and promise of God form the preamble to the whole book, which is linked on to the conclusion of the Pentateuch by the introductory words, “And it came to pass after the death of Moses, the servant of the Lord,” though it is not so closely connected as to warrant the conclusion that the two works have been written by the same author.
