Joshua 1:18

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.

The book begins with the history, not of Joshua's life (many remarkable passages of that we had before in the books of Moses) but of his reign and government. In this chapter, I. God appoints him to the government in the stead of Moses, gives him an ample commission, full instructions, and great encouragements (Jos 1:1-9). II. He accepts the government, and addresses himself immediately to the business of it, giving orders to the officers of the people in general (Jos 1:10, Jos 1:11) and particularly to the two tribes and a half (Jos 1:12-15). III. The people agree to it, and take an oath of fealty to him (Jos 1:16-18). A reign which thus began with God could not but be honourable to the prince and comfortable to the subject. The last words of Moses are still verified, "Happy art thou, O Israel! Who is like unto thee, O people?" Deu 33:29.

1:18 Disobeying God’s chosen ruler was treason against God himself.
