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 23:33 Then the Lord spoke to Moses, saying, 34 “Speak to the children of Israel, saying: ‘The fifteenth day of this seventh month shall be the Feast of Tabernacles for seven days to the Lord. 35 On the first day there shall be a holy convocation. You shall do no customary work on it. 36 For seven days you shall offer an offering made by fire to the Lord. On the eighth day you shall have a holy convocation, and you shall offer an offering made by fire to the Lord. It is a sacred assembly, and you shall do no customary work on it.
37 ‘These are the feasts of the Lord which you shall proclaim to be holy convocations, to offer an offering made by fire to the Lord, a burnt offering and a grain offering, a sacrifice and drink offerings, everything on its day— 38 besides the Sabbaths of the Lord, besides your gifts, besides all your vows, and besides all your freewill offerings which you give to the Lord.
