선지자 하나냐가 그 해 칠월에 죽었더라
Rashi on Jeremiah
in that year, in the seventh month Is it not so that the seventh month is not of the year? Rather, he died on the day preceding Rosh Hashanah and commanded his children to hurry him after Rosh Hashanah, but not before, and they should conceal his death on that day in order to make Jeremiah’s prophecy appear false.
