The Third Feast - the Feast of Tabernacles (7th Month)
7+7+7

The third feast that God commanded Israel to celebrate is known as the Feast of Tabernacles. The timing of this feast is similar to the first feast. An example of this feast is found in 

Leviticus 23:33-44:


33 And the LORD spake unto Moses , saying,
34 Speak unto the children of Israel, saying,
The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the LORD.
35 On the first day shall be an holy convocation: ye shall do no servile work therein.
36 seven days ye shall offer an offering made by fire unto the LORD: on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the LORD: it is a solemn assembly; and ye shall do no servile work therein.
37 These are the feasts of the LORD, which ye shall proclaim to be holy convocations, to offer an offering made by fire unto the LORD, a burnt offering, and a meat offering, a sacrifice, and drink offerings, every thing upon his day:
42 Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths:
43 That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt : I am the LORD your God.


The third feast takes place in the 7th month during the 3rd 7-day period of the month. Again, the first feast and the third feast take place in the third 7-day period of the month. This is a period of time that Yahweh has used in the Bible to time some of His important acts in the Bible.


The three feast that Yahweh commanded Israel to observe reflects His 2+1 sequence by their designs. Two of the feasts take place in the 3rd - 7 day periods of the lunar month. The Feast of weeks is different.
