Many Scholars claimed that Israel was only 215years in Egypt.
This is written to proof that Israel was afflicted for 400years in Egypt.
[Joseph being 17years old was the first Israelite sold into Egypt. which was 30years after Jacob sojourned in Haran.]
Genesis 15:13,14:"And He said unto Abram, Know of a surety that thy seed shall be a stranger in a land[EGYPT] that is not theirs, and shall serve them; and they shall afflict them four hundred years; And also that nation[EGYPT], whom they shall serve, will I judge: and afterward shall they come out with great substance."
Acts 7:6:"And God spake on this wise, That his seed should sojourn in a strange land[EGYPT]; and that they[EGYPTIANS] should bring them into bondage, and entreat them evil four hundred years."
Gen15:16: "But in the fourth generation they shall come hither[back to Canaan where Abram was already in that promised land] again: for the iniquity of the Amorites is not yet full."
This next verse was fulfilled by Moses son of Jochebed, daughter of Levi, son of Jacob. Moses was the 4th Generation from Israel Jacob.
It is important to note that Israel Jacob's sojourning started 30yearsbefore Joseph went into Egypt.
Exodus12:40,41:"Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years.
And it came to pass at the end of the four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of the Lord went out from the land of Egypt."
Note that there were commas separating the comment ", who dwelt in Egypt," from the 430years sojourning which is a separate calculations but was included into the total 430years of sojourning.
Therefore 30years sojourning of Israel which began when Jacob sojourn in Haran for 2x7years when Joseph was born and he decided to leave Laban but stayed 6 more years.
14+16yrs = 30years sojourning before Joseph sold into Egypt at 17th year plus 400 years of affliction is 430years.
Note: When Joseph was 17years, he was the first seed that entered Egypt.
Joseph was in Egypt for 93years because he died at 110years old. Genesis 50:22&26.
Pls note that Levi, Kohath and Amran's very old age was recorded as 137yrs, 133yrs and 137 years specially by God. See Exodus 6:16,18,20. God is giving us concrete proof that there could be 400yrs of affliction in Egypt. the Nation which was prophesied in Genesis that God shall judge. see Genesis 15:13.
Exodus 7:7 :"And Moses was fourscore years old, and Aaron fourscore and three years old, when they spake unto Pharaoh."
adding Moses 80yrs age makes the time of sojourning 407yrs+80yrs=487yrs even more possible.
Pls note that Levi had a daughter named Jochebed [Glory of God] see Exodus 6:20 & Numbers 26:59.
What makes Jochebed the Glory of God? Could it be possible that she lived long and gave birth to Aaron and Moses at very old age of 200 years old?
This could represent the Church or Woman which is giving birth to a son 2000yrs later as in Revelation 12.
Since the time started from Joseph being 17yrs old when seed was in Egypt. Then if Levi gave birth to Jochebed after Joseph's death, then it is very possible that Levi could have been 137years old when Jochebed was born in Egypt.
Joseph was 93years in Egypt [went into Egypt when he was 17years old and died 110years old] + 27years later Levi still alive[assuming Levi age 137years born same age as Joseph] + 200yrs Jochebed + 80years Moses = 400years in Egypt.
Many Bible Scholars argued that it is impossible for 400years in Egypt because Genesis 46 stated Kohath already born in Egypt and if Kohath + Amran + Moses the max life span in Egypt is only 133+137+80=350years.
This is not an absolute fact because
Bible Scholars had not taken into account that Joseph was already in Egypt since 17years old and so 23years of Joseph's suffering had been excluded in their calculations.
Furthermore, Joseph was still ruler of Egypt for many years with his family.
The names of Jacob's sons' wives [at least 10] were not mentioned and only significant names was recorded by Moses when he wrote the book of Genesis.
Joseph could have seen Kohath being born [so called went into]
during his 70years with his family together in Egypt. [110-40=70years] Note Joseph 30years old became ruler of Egypt. Gen 41:46. +7yrs plenty +2yrs famine = 39yrs old. Genesis:45:11. So Joseph met his family at his 40th year.
Note that Genesis 46 has total of 70+12[sons' wives] souls.
Gen46:26 CONFIRMED "ALL the SOULS that came with JACOB" was 70 and this includes "sons and SONS' WIVES"!
Note: Joseph's wife+2sons was added to the 66 souls to count 70souls.
So 10 or more children and grandchildren may have not been born yet at the time Jacob entered Egypt.
Joseph ruled for 70years and there may have 70 names of Jacob's children plus grandchildren and so it is included in Genesis 46.
Although sons' wives' names not specifically mentioned but their souls are counted in the record.
Note that The sum of Jacob's sons & daughters 33 souls of Leah + 16 souls of Zilpah + 14 souls of Rachel + 7 souls of Bilhah = 70 souls. Gen46:15,18,22&25
It is very likely that their names were recorded to show that God had also given Joseph while he was still a ruler for more than 70years in Egypt and he saw Jacob's 70 children/grandchildren.
Joseph have not seen Jochebed the daughter of Levi yet.
The list of 66 souls of Israel Jacob's sons and wives had not included the names of Jacob's sons' wives who are at least ten. Although the total sum of the souls that came to Egypt was mentioned as 70 souls, the wives of Jacob's sons and grandsons were counted but their names not as significant. That is why the list did not specifically record their names and only important names such as Benjamin & Levi's children were recorded.
There were ten children born by Benjamin and three sons born by Levi.
With God giving us the old ages of Levi, Kohath, Amran and Moses...
Moses wrote the books few hundred years later and so he could give the names of Israel's children/grandchildren in the chapter 46[though chapters had not been used till modern times]
This narration of Jacob's children may be confusing at first but is not if you undersatnd the historical truth that Joseph was ruler and names were RECORDED in books which may be available during Moses' times.
God bless you in seeking all truth in His Word.
