"in its time": from one Sabbath night to the next, as, indeed, occurred in the days of Queen Hilni. And why all this? So as not to leave an opening for future generations to say: "What is the reward for all of the mitzvoth?" But (Vayikra 26:3-4) "If you walk in My statues and keep My commandments and do them; then I will give your rains in their (proper) times." (Devarim 11:12-19) "And it shall be if you hearken, hearken to My mitzvoth … then I shall give the rain of your land in its (proper) time, yoreh and malkosh."
