לָהֶ֣ם לְ֭בַדָּם נִתְּנָ֣ה הָאָ֑רֶץ וְלֹא־עָ֖בַר זָ֣ר בְּתוֹכָֽם׃
kepada merekalah saja negeri itu diberikan, dan tidak ada orang asing yang lewat di tengah-tengah mereka.
Rashi
וזאת ליהודה AND THIS IS FOR JUDAH — He mentioned Judah immediately after Reuben because both of them made confession of the wrong that was theirs, as it is said, (Job 15:18-15:19) “Because wise men have told their sins … unto them alone [the land was given] and no stranger passed amidst them”. Further our Rabbis explained that during the whole forty years that Israel was in the wilderness Judah's bones were moving about in his coffin because of the excommunication that he had invoked upon himself, as it is stated that he said "If I do not bring him unto thee … I shall be sinning against my father all days" (cf. Rashi thereon: “also in the world to come”). Moses said, “Who brought it about that Reuben confessed his sin?” Judah, etc. (Sotah 7b; Bava Kamma 92a).
