But, what about the verse we read in Genesis 15 mentioning 400 years? How is that reckoned? Notice that verse again. “And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not
theirs, and shall serve them; and they shall afflict them four hundred years.”
We find another account from Stephen, Acts 7:6. It states, “And God spake on this wise, That his seed should sojourn in a strange land; and that they should bring them into bondage, and entreat them evil four hundred
years.”
Both verses very specifically indicate the four hundred years is to be regarding “thy seed” or “his seed”.
As we just read in Genesis 21 Isaac was born when Abraham was 100 years old.
Before we go through this let us go back to Exodus 12:41. It is stated in this verse that the event took place “even the selfsame day.”
The covenant with Abraham occurred on the very same day, the 14th day of the first month at even.
And, as we will see, the sacrifice of Isaac also was at the time of the later to be commanded Passover sacrifice.
It also appears that it was in the springtime when Jacob and his family entered Egypt to live there. Undoubtedly this event occurred on “the same day.” (See Gen. 45:6)
The day Isaac was “selected” to be the sacrifice I believe was the 10
th
day of the first month. That was the day the Passover lamb was to be selected (Ex. 12:3) and the same day Jesus Christ rode into Jerusalem
and was “selected” by the Father (see John 12:28).
God does things on schedule at His appointed times. He had promised to take the descendants of Abraham from the land in which they would be enslaved 430 years after His promise to Abraham. And, we
have seen that He was doing it EXACTLY to the very day. God had been very definitely watching and vigilantly working all events out so that it happened on His timetable.
God spoke to Moses from the “burning bush.” He said that He had seen the affliction of His people and “I am come down to deliver them out of the hand of the Egyptians...” (Ex. 3:8)
He had not forgotten them and everything was on schedule per the time God had prophesied. He had prepared Moses. He had worked it out so that Moses would have the necessary training for the Exodus;
acquired in the palace of Egypt and backside of the desert (40 + 40 yrs.)
Exodus 3:1 tells us that Moses kept the flocks of his father in law, Jethro, in “the backside of the desert, and came to the mountain of God, even to Horeb.” Horeb and Sinai are used almost interchangeably, although
there is some discussion as to whether Horeb may have been the name of the mountain range and Sinai the specific mount. Nevertheless, it was in this very area that Moses had spent time with the flocks and
had become very familiar with the territory.
In addition to “bringing Israel out of Egypt” God also was committed to fulfill His promise to Abraham to judge “that nation, whom they shall serve,” (Gen. 15:14).
Also, He had promised that after He had done that, the people would “come out with great substance.” When God spoke to Moses from the burning bush He repeated this promise, that the people would be given
favor in the sight of the Egyptians and they would “not go empty.” (Ex. 3:21)
It all came down to “the selfsame day.” (Ex. 12:41) What a marvelous and wonderful God who was continually vigilant and observing His people, who was working out ALL the many events that took place over
430 years. A magnificent God who had everything culminate on the exact day the 430 years, the 400 years and the last 210 years were up. It is the same for you and I beloved!
