Midrasz do Rodzaju 48:13

... [What about all] the praise of Joseph, who exceeded in the honor of his father? And yet he did not enter into him all the time, such that were it not that they came to tell him, "Your father is sick," he would not have known! Rather this is to inform you of his righteousness. For he did not want to be alone with his father, lest he say to him, "How did your brothers act with you?" And [then] he would curse them.... Hence he did not go to his father all the time.)

"But with a lot, etc." (Numbers 26:55). This is [the meaning of] that which is stated (Proverbs 18:18), "The lot puts an end to strife." Since a sign was written for each and every tribe from Yaakov - "Zevulun will dwell on the shore of the seas" (Genesis 49:13); "Yissachar is a boney donkey, etc." (Genesis 49:14); "From Asher, his bread is fat" (Genesis 49:20) - you are only permitted to divide [the land] by the lot. And there were miraculous acts in the lottery: Elazar the Priest wears the Urim and Tumim. And the slips of the lottery were in front of Yehoshua, as stated (Joshua 18:6) "And I will cast the lot for you here in front of the Lord, our God." But before the lot went up, Elazar said with the holy spirit, "The lot of tribe x is coming up, to take place y." And Yehoshua would extend his hand and [it] would come up [into his hand. It was] as it is stated (Joshua 19:51), "These are the inheritances that Elazar the Priest and Yehoshua ben Nun apportioned." And this was [even] more; that the lot would yell out at the time that it went up, "I am the lot of tribe x; I have gone up to it in place y." And from where [do we know] that the lot speaks? As it is stated (Numbers 26:56), "By the mouth of (according to) the lot."
