Ending the wrath; ending the decree[1]
ותרגנו באהליכם ותאמרו בשנאת ד’ אותנו הוציאנו מארץ מצרים
They grumbled in their tents and said: “With Hashem’s hatred of us He took us out of the land of Egypt”[2]
We find a parallel verse in Psalms to the one in our parsha, which says: “They grumbled in their tents; they didn’t listen to the voice of Hashem. He raised His hand [in oath] against them to cast them down in the wilderness and to cast down their descendants amongst the nations, scattering them in the lands”[3]. Rashi there explains that at that very moment, the destruction of the Temple was decreed. That very night that the Jews cried in vain (believing the spies that the land of Israel isn’t worth conquering) was Tisha B’Av. Hashem said that since they cried for no reason, they will have a reason to cry for the generations.
