Comentario sobre Josué 11:18

For many days did Yehoshua. This verse was said to criticize Yehoshua, who intended to delay the conquest of the land, in order to lengthen his days, for it is said, “And you will apportion it to them.”⁶It took seven years for Yehoshua to conquer the whole land. Our Sages say that he could have conquered the land more quickly. It did not have to take seven years. Yehoshua was reluctant to complete the conquest of the land and divide it between the tribes. He was afraid that once he completed it, he would die. He knew his mission in life was to bring Bnei Yisroel into Eretz Yisroel and settle them there. Once his mission was completed, his life would have no further purpose. See Devorim 31:7 Because he was reluctant to complete the conquest, God punished him, and as soon as the apportioning of the land was completed he died. He was then one hundred and ten years old. Were it not for this, he would have lived ten more years, till one hundred and twenty as did his master, Moshe. From Midrash Tanchumah.
