Joshua 1:9

“Have not I commanded thee? etc.] The above things, to go over Jordan with the people into the land of Canaan, and to observe the law of Moses in all things, and to be of good courage, which is again repeated; consider who it is that has given these orders and instructions, the great Jehovah, the everlasting I AM, who is faithful to his promises, and able to perform. The consideration of which would serve to animate him to the work he was called unto, to encourage his faith in God, to engage in his service cheerfully and readily: be strong, and of a good courage; (see Gill on “<060106>Joshua 1:6”); (see Gill on “<060107>Joshua 1:7”). be not afraid, nor be thou dismayed; at his enemies,…”

“I commanded thee - I whom thou art obliged to obey: I who can carry thee through every thing I put thee upon: I of whose faithfulness and almighty power thou hast had large experience? Joshua 1:10”

“1:9 As the Israelites entered Canaan, they would fight the worshipers of the Canaanite gods, but they were afraid these gods would grant the Canaanites victory in battle. In reassuring Joshua, God used his personal name the Lord (Hebrew Yahweh; see study note on Exod 3:15) to remind Joshua that the Lord was more powerful than any false gods the Canaanites might invoke. • your God is with you: God’s continuous presence made it possible for Joshua to heed God’s instruction.”

“Have: Deu 31:7, Deu 31:8, Deu 31:28; Jdg 6:14; Sa2 13:28; Act 4:19 Be strong: Jos 1:6, Jos 1:7 be not: Gen 28:15; Deu 20:1; Psa 27:1, Psa 27:2; Jer 1:7, Jer 1:8 for the Lord: Psa 46:7; Isa 43:1, Isa 43:5 Joshua 1:10”

“In conclusion, the Lord not only repeats His exhortation to firmness, but the promise that He gave in Jos 1:5 and Jos 1:6. "Have I not" (nonne) is a rhetorical mode of saying, "Behold, I have," the assurance being clothed in the form of an affirmative question. On the words "be not afraid," etc., see Deu 31:6 and Deu 31:8. Joshua 1:10”
