The temporary temple[1]
לא-יסור שבט מיהודה ומחקק מבין רגליו עד כי-יבא שילה ולו יקהת עמים
The scepter shall not depart from Yehuda, nor the leader[2] from between his feet. Not until Shiloh will come, for he shall congregate nations[3]
The Ramban shares with us[4] an interesting insight into Jewish history. While there was still a Jewish monarchy, there were many generations of kings which were not from the tribe of Yehuda. They were in fact violating the blessing, and really the last will and testament[5], of Yaakov. How so? Yaakov, upon his deathbed, prophetically blessed his twelve sons. Regarding Yehuda, he said that the scepter shall not depart from Yehuda. Meaning, the kingship. All Jewish kings are to come from Yehuda. This wasn’t a promise that the kingship would never leave his tribe, as we see it didn’t come true. Rather, it was in essence a command that only Judean kings are valid, and all others are violating this directive.
