147: He’s not ungrateful in the least, he’s makir tovah to HaShem for the Chasadim He did for us, letting us continue to live in the holy land (whether their efforts made it better or worse is up to debate), in spite of the efforts of those who tried to “help” Him, and further worse, claiming kochi v’otzem yadi. So he (and most of Klal Yisroel) thanks HaShem directly, EVERY DAY, for His open miracles and kindness he shows us. And we don’t extoll praise on those mechalelei Shabbos, who only stood in the way, and thereafter laid claim to kochi v’otzem yadi, on the day that they decided should be declared as such.
No, Yeravam’s invention – ????? ??? ??? ???? – has not made it into a Torah observant Jew’s calendar, neither should this one, a desperate attempt to hijack the chasadim HaShem has shown , and instead pay homage and heed to sonei hadas.
