Exodus 7:1-12:40 describes the ten plagues God had to send on the Egyptians before they would let the Israelites leave to go to the land God had promised them. Yet even after all of this suffering Pharaoh changed his mind about freeing the Israelites and tried to bring them back into slavery. Exodus 14:5-31 tells how God opened the Red Sea to allow the Israelites to escape and then allowed the sea to return to drown Pharaoh and his army. Israel was finally free to go to its own land and Egypt was in ruins with its ruler dead.
But God’s judgments had another result.
“Behold, about this time tomorrow I will cause very heavy hail to fall, such as never has been in Egypt from the day it was founded until now.Now therefore send, get your livestock and all that you have in the field into safe shelter, for every man and beast that is in the field and is not brought home will die when the hail falls on them.” Then whoever feared the word of the Lord among the servants of Pharaoh hurried his slaves and his livestock into the houses, but whoever did not pay attention to the word of the Lord left his slaves and his livestock in the field.
Not all of the Egyptians were as hard hearted as Pharaoh. Some of them feared God and took steps to protect themselves. When the Isrealites left Egypt they left behind a group of people who believed in the true God.
Now Joseph had been brought down to Egypt, and Potiphar, an officer of Pharaoh, the captain of the guard, an Egyptian, had bought him from the Ishmaelites who had brought him down there.
Joseph’s brothers had sold him to a caravan of Ishmaelites who were on their way to Egypt. When the Ishmaelites reached Egypt they sold Joseph to Potiphar. We are told two things about him: he was the captain of Pharaoh’s guard and he was an Egyptian. Saying he was captain of the guard makes sense. It gives us some information about who Potiphar was. But saying he was an Egyptian seems redundant. He lived in Egypt and was an officer of Pharaoh. What could he be except an Egyptian?
Nearly everyone knows how Moses freed the Israelites from Egyptian slavery. Not many know that Moses had made a previous attempt to free them and had failed.
One day, when Moses had grown up, he went out to his people and looked on their burdens, and he saw an Egyptian beating a Hebrew, one of his people. He looked this way and that, and seeing no one, he struck down the Egyptian and hid him in the sand.
When he went out the next day, behold, two Hebrews were struggling together. And he said to the man in the wrong, “Why do you strike your companion?”
He answered, “Who made you a prince and a judge over us? Do you mean to kill me as you killed the Egyptian?”
Then Moses was afraid, and thought, “Surely the thing is known.” When Pharaoh heard of it, he sought to kill Moses. But Moses fled from Pharaoh and stayed in the land of Midian.
This appears to be nothing more than Moses seeing an act of cruelty and intervening but the New Testament gives more information.
