(6) Be strong and resolute, be not in fear or in dread of them; for the LORD your God marches with you: He will not fail you or forsake you. (7) Then Moses called Joshua and said to him in the sight of all Israel: "Be strong and resolute, for it is you who shall go with this people into the land that the LORD swore to their fathers to give them, and it is you who shall apportion it to them...."
(כג) וַיְצַ֞ו אֶת־יְהוֹשֻׁ֣עַ בִּן־נ֗וּן וַיֹּאמֶר֮ חֲזַ֣ק וֶֽאֱמָץ֒ כִּ֣י אַתָּ֗ה תָּבִיא֙ אֶת־בְּנֵ֣י יִשְׂרָאֵ֔ל אֶל־הָאָ֖רֶץ אֲשֶׁר־נִשְׁבַּ֣עְתִּי לָהֶ֑ם וְאָנֹכִ֖י אֶֽהְיֶ֥ה עִמָּֽךְ׃
(23) And He charged Joshua son of Nun: "Be strong and resolute; for you shall bring the Israelites into the land that I promised them on oath, and I will be with you."
Rashi on Deuteronomy 31:7
for you shall come with this people: “For you shall come with this people,” [hence, the אֶת here means “with.” Accordingly, Moses’ statement of leadership role to Joshua can be understood as follows]: Moses said to Joshua, “The elders of the generation will be with you, [for] everything should be done according to their opinion and counsel.” In contrast, however, the Holy One, Blessed is He, said to Joshua,“For you shall bring (תָּבִיא) the children of Israel to the land which I have sworn to them” (verse 23). [God’s statement of leadership role to Joshua here means:] “You shall bring them [even if it is] against their will! Everything depends [only] upon you; [if necessary,] you must take a rod and beat them over their heads! ...”- [Sanhedrin 8a]
"At the end of his life, Moses recognized one great failure of his leadership. He had taken the Israelites out of Egypt, but he hadn’t taken Egypt out of the Israelites. He had changed his people’s fate, but he hadn’t changed their character. He now realized that for this to happen there would have to be a different kind of leadership, one that handed back responsibility to the people as a whole, and to the elders in particular. So long as there is a Moses performing miracles, the people do not have to accept responsibility for themselves. In order for them to grow, Joshua would have to engage in participative leadership, encouraging diverse views and listening to them, even if that meant going more slowly." - Rabbi Lord Jonathan Sacks
"Both God and Moses wanted Joshua to know that true leadership cannot be a one-sided affair, be it the pursuit of consensus or command-and-control. It must be a deft balance of both....In short, leadership is not simple. It is complex because it involves people and people are complex. You have to listen, and you have to lead. You have to strive for consensus but ultimately, if there is none, you must take the risk of deciding...." - Rabbi Lord Jonathan Sacks
