Joshua 1:1 - Wesley's Explanatory Notes

After the death of Moses — Either immediately after it, or when the days of mourning for Moses were expired. Joshua was appointed and declared Moses's successor in the government before this time; and here he receives confirmation from God therein. The servant of the Lord — This title is given to Moses here and Joshua 1:2, as also Deuteronomy 34:5, and is repeated not without cause, to reflect honour upon him, to give authority to his laws and writings, in publishing whereof he acted as God's servant, in his name: and that the Israelites might not think of Moses above what was meet, remembering that he was not the Lord himself, but only the Lord's servant; and therefore not to be too pertinaciously followed in all his institutions when the Lord himself should come and abolish part of the Mosaical dispensation; it being but reasonable that he who was only a servant in God's house, should give place to him who was the son, and heir, and Lord of it. The Lord spake — Either in a dream or vision, or by Urim, Numbers 27:21. Moses's minister — Who had waited upon Moses in his great employments, and thereby been privy to his manner of government, and so prepared for it.
