There are 3 chapters of Exodus which deal with the 3 day sacrifice request...
16 You go, and you must gather the older
men of Israel, and you must say to them, 'Jehovah the God of your forefathers
has appeared to me, the God of Abraham, Isaac and Jacob, saying: I will without
fail give attention to you and to what is being done to you in Egypt.
17 And so I say, I shall bring you up out of affliction by the Egyptians to the land of the Canaanites and the Hittites and the Amorites and the Perizzites and the Hivites and the Jebusites, to a land flowing with milk and honey.'
18 And they will certainly listen to your voice, and you must come, you and the older men of Israel, to the king of Egypt, and you men must say to him, Jehovah the God of the Hebrews has come in touch with us, and now we want to go, please, a journey/way/road of 3 days [day counts 1x in the account] into the wilderness/pasture, and we want to sacrifice to Jehovah our God (Exodus 3:18).
However, they went on to say: The God of the Hebrews has come in touch with us. We want to go, please, a journey/way/road of 3 days [day counts 5x in the account] into the wilderness/pasture and sacrifice to Jehovah our God; otherwise he may strike at us with pestilence or with sword (Exodus 5:3).
25 Finally Pharaoh called Moses and Aaron
and said: Go, sacrifice to your God in the land.
26 But Moses said: It is not admissible to do so, because we would sacrifice to Jehovah our God a thing detestable to the Egyptians. Suppose we would sacrifice a thing detestable to the Egyptians before their eyes; would they not stone us?
27 We shall go a journey of 3 days [Day counts 2x in the account] into the wilderness and we shall definitely sacrifice to Jehovah our God just as he has said to us.
28 Pharaoh now said: I -- I shall send you away, and you will indeed sacrifice to Jehovah your God in the wilderness. Only do not make it quite so far away that you are going. Make entreaty in my behalf (Exodus 8).
In the literal meaning, Pharaoh supposed that Moses wanted to take a 3 literal day journey into the wilderness and then make a sacrifice to his God. Now Mount Sinai in Arabia was 3 days direct journey from Baal-Zephon, the far side of the Red Sea Crossing. The Sinai Peninsular, although not the Egypt itself, was within the jurisdiction of greater Egypt. So the wilderness began at Baal Zephon - see U249.
However God may have been asking Moses to take a journey of 3 worship system days, the 3 days of the Tabernacle, Solomon's and Zerubbabel's temples. These being the last 3 sacrificial days for Israel before Jesus who ended all animal sacrifices.
The greater meaning of Exodus 5 involves 3 literal days, since the word 'day' counts 5x and is hopefully literal in the literal meaning. These are the 3 days of the 3 Passover celebrations on 2017Elul14 and 2017Tishri14 and 2017Heshvan14. Because Moses said...
9 Then Moses said: With our young people and our old people we shall go. With our sons and our daughters, with our sheep and our cattle we shall go, for we have a festival to Jehovah [The Passover/cakes was the only festival they had at the time of the Exodus] (Exodus 10).
On all 3 of these days the Passover victims (1NC saints) are slaughtered by being baptised into the physical death of the 1NC. In fact all of the 6,000 Passover lambs will presumably have to die within a year of their New Passover baptism, in order that they are actually sacrificed at a year old - in solar terms. The statute for the Passover was...
5 The sheep should prove to be sound, a male, a year old, for you (Exodus 12).
The scriptures do record a journey of 3 days into the wilderness from Baal-Zephon to Shur...
22 Later Moses caused Israel to depart
from the Red Sea and they went out to the wilderness of Shur and marched on for
3 days in the wilderness, but they did not find water.
23 In time they came to Marah, but they were not able to drink the water from Marah because it was bitter. That is why he called its name Marah.
24 And the people began to murmur against Moses, saying: What are we to drink?
25 Then he cried out to Jehovah. So Jehovah directed him to a tree, and he threw it into the water and the water became sweet. There he established for them a regulation and a case for judgment and there he put them to the test (Exodus 15).
But they are not recorded as making any sacrifice on the third day. This first sacrifice was the validation of the law covenant in 1513Sivan. So really the sacrifices began after the law covenant was entered into.
The bitter water was the law of works of Moses, entrance to Isaac with but with a curse. The sweet water is the law of faith in Christ, who is the tree, who got uprooted from heaven and subjected to the law. This tree ended the law and its curse.
24 And he must make the woman drink the bitter water that brings a curse, and the water that brings a curse must enter into her as something bitter (Numbers 5).
13 Christ by purchase released us from the curse of the Law by becoming a curse instead of us, because it is written: Accursed is every man hanged upon a stake (Galatians 3).
61 And said: This man said: I am able to throw down the temple of God and build it up in three days (Matthew 26).
40 And saying: O you would-be thrower-down of the temple and builder of it in three days, save yourself! If you are a son of God, come down off the torture stake! (Matthew 27).
58 We heard him say: I will throw down this temple that was made with hands and in three days I will build another not made with hands (Mark 14).
29 And those going by would speak abusively to him, wagging their heads and saying: Bah! You would-be thrower-down of the temple and builder of it in three days' time (Mark 15).
19 In answer Jesus said to them: Break down this temple, and in three days I will raise it up (John 2).
The literal fulfillment was the temple of FDS1, the cornerstone of which was Jesus. This has confused the writer in the past but Jesus is also the foundation stone of this temple. He is the, the rock mass, the greater threshing floor of Ornan. Jesus becomes upgraded from the first cornerstone to the rock mass. And then Peter is upgraded from the first stone after the first cornerstone to the first cornerstone. This occurs when Peter ceases to be one of the 12 and becomes instead the head of the wife of Jesus. The symbolic fulfillment is the temples of FDS2,3,4 in three different ‘days’, to the day of the first temple. After all there were 4 cornerstones. The other three were St. Paul, Charles Russell and Gordon Ritchie. But the symbolism of these cornerstones relates to an overall Christian temple, which comprises all 4 of the 4 temples of FDS1,2,3,4 and which obviously has 4 cornerstones, one foundation rock mass and 4 walls etc. Jesus was a player manager in the case of FDS1, the first Christian sub-temple, so he was both the foundation rock mass and the first cornerstone. But in the other three sub-temples of the overall temple he was just the manager and Paul, Russell and Ritchie were the team captains, the players, the cornerstones. Things are just as in the case of the request of Moses to Pharaoh at the start of this section. In fact the Christian fulfilment is a greater meaning of Moses' request.
