The 7thday of Sukkot is Hoshana Rabba and is the climax of the feast. Hoshana Rabba is all about the #7 & completing the purposes of God. 7 = completion/fullness/ending in the Bible. Sukkot takes place in the 7thmonth, it has 7 days. All the sacrifices for the feast of Sukkot or divisible by 7 & Hoshana Rabba has 7 sacrifices on that day. Just like all the other feasts in the fall being linked to the End Times and Revelation, so is Hoshana Rabba. And Revelation is also all about the # 7 too! 7 angels, 7 lampstands, 7 bowls, 7 seals, 7 trumpets.
LEVITICUS 2333 Adonai said to Moshe, 34 “Tell the people of Isra’el, ‘On the fifteenth day of this seventh month is the feast of Sukkot for seven days to Adonai. 35 On the first day there is to be a holy convocation; do not do any kind of ordinary work. 36 For seven days you are to bring an offering made by fire to Adonai; on the eighth day you are to have a holy convocation and bring an offering made by fire to Adonai; it is a day of public assembly; do not do any kind of ordinary work.
39 “ ‘But on the fifteenth day of the seventh month, when you have gathered the produce of the land, you are to observe the festival of Adonai seven days; the first day is to be a complete rest and the eighth day is to be a complete rest. 40 On the first day you are to take choice fruit, palm fronds, thick branches, and river-willows, and celebrate in the presence of Adonai your God for seven days. 41 You are to observe it as a feast to Adonai seven days in the year; it is a permanent regulation, generation after generation; keep it in the seventh month. 42 You are to live in sukkot for seven days; every citizen of Isra’el is to live in a sukkah, 43 so that generation after generation of you will know that I made the people of Isra’el live in sukkot when I brought them out of the land of Egypt; I am Adonai your God.
