I will not permit the people to be defeated. Another explanation: you stood yourself in the camp and did not go out with them,⁴When you sent the men to capture the city of Ai, you remained at the camp and did not lead them. and I had said, ‘Who will take them out [to war] and who will bring them [back].’⁵Bamidbar 27:17. ‘For you will bring the Bnei Yisroel— and I will be with you.’⁶Devorim 31:23. ‘For he will cross over before this people, and he will spur them on to inherit.’⁷Devorim 3:28. If you go before them, they will succeed, and if not, they will not succeed. Another explanation: Get yourself up, it is your fault [because of you] that this has happened to them.
