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.
