Musar su Deuteronomio 28:36

לא יסור שבט מיהודה ומחוקק מבין רגליו עד כי יבא שילה . It is of the utmost importance to understand the true meaning of this verse in order to be able to refute apostates, Christians, etc. Nachmanides expresses himself as follows on this subject: The meaning of this verse is not that the kingdom will never depart from Yehudah. After all, the Torah writes very clearly in Deuteronomy 28,36: "The Lord will drive you and the king you have set over yourself, to a nation unknown to you or to your ancestors." If both Israel and its king will be in exile, then they will obviously not have kings or aristocracy. History has shown that Israel has been in this condition for many hundreds of years. No prophet has ever assured Israel that it would not be exiled so that the tribe of Yehudah could continue to rule over it. What the verse does tell is that the sceptre, symbolising kingdom, would not depart from the hands of Yehudah in favour of a member of another tribe. The same is true of the second half of the verse which discusses scribes. Any scribe in Israel who is authorised by the signet ring of the king will be so authorised by a king from the tribe of Yehudah. This state of affairs will continue until his son, the Messiah, will arrive, at which time the kingdom of Yehudah will extend over all the nations. The word שבט is an allusion to David, the first king from the tribe of Yehudah, whereas the word שילה, his son, is the Messiah around whom all the nations will gather. Thus far Nachmanides.
