Immediate joy[1]
…והיית אך שמח
…and you shall be only joyous[2]
There’s an interesting Midrash[3] that compares the time between Pesach and Shavuos, and the time between Sukkos and Shemini Atzeres. The time between Pesach and Shavuos is fifty days, whereas there is no break between Sukkos and Shemini Atzeres. Why is this so? The Midrash answers with a parable. This is similar to a king with many kids. Some are married[4] and live far away, and some are married and live close by. When those who live close by come to visit, when came time to depart the King would let them go without difficulty, since anyways they live close by. However, those who live far away, when they would visit and it came time to leave, the King would hold them back. He would plead with them to stay one more day, due to the distance between them.
