The Israelites ended up staying in Egypt 430 years
Exo 12:40
as God had told Abraham they would.
Gen 15:13-14
To give you an idea of just how long that is, 430 years ago, there were ZERO English speaking towns in all of North America. Jamestown, Virginia was not settled until 1607.
During those 430 years, the 70 people who came to Egypt with Jacob had become over 600,000.
Exo 12:37
Then a new king, who knew nothing of Joseph, came to power in Egypt. Exo 1:8
[The new Pharaoh] said to his subjects, “… let us deal shrewdly with [the Israelites] to stop their increase; otherwise, in time of war they … may join our enemies to fight against us…” Exo 1:9-10
So …
The Egyptians, … reduced [the Israelites] to cruel slavery, Exo 1:12-13
Yet the more [the Israelites] were oppressed, the more they multiplied and spread. The Egyptians, then, dreaded the Israelites Exo 1:12
Pharaoh then commanded all his subjects, “Throw into the river every boy that is born to the Hebrews, but you may let all the girls live.” Exo 1:22
A certain baby boy was born; and saved out of the river.
Exo 2:1-10
Pharaoh’s daughter, … adopted him as her son and called him Moses; … Exo 2:10
“When [Moses] was forty years old, he decided to visit his kinsfolk, the Israelites. Acts 7:23
… [Moses] … saw an Egyptian striking a Hebrew, Exo 2:11
… [Moses] slew the Egyptian … Exo 2:12
Pharaoh, … heard of the affair and sought to put [Moses] to death. But Moses fled from [Pharaoh] and stayed in the land of Midian Exo 2:11-15
in the desert of the Sinai peninsula.
By faith [Moses] left Egypt … Hebrews 11:27
Forty years [after Moses left Egypt to live in Midian],
(when he was 80 years old)
an angel appeared to [Moses] in the desert near Mount Sinai in the flame of a burning bush. When Moses saw it, he was amazed at the sight, and as he drew near to look at it, the voice of the Lord came, ‘I am the God of your fathers, the God of Abraham, of Isaac, and of Jacob.’ … I have come down to rescue [my people].
Come now, I will send you to Egypt.’ Acts 7:20-34
Moses, …, said to the LORD, “… I am slow of speech and tongue.” … “If you please, Lord, send someone else!” Exo 4:10-16
… only after long debate does Moses attune his own will to that of the Savior God. … # 2575
Moses … learns how to pray: he balks, makes excuses, above all questions: # 2575
Questioning God is fine, as long as we do so sincerely, honestly, humbly. Moses was absolutely sincere, completely honest with God.
[God trusted] Moses [because] “Moses was very humble, more so than anyone else on the face of the earth.” # 2576
see also Exo 12:3
Moses [conversed] with God often and at length # 2576
From this intimacy with the faithful God, slow to anger and abounding in steadfast love, Moses drew strength and determination #2577
