How did Pharaoh's daughter take away Moses to bring up as her own?
When Moses' mother could no longer hide him, she floated him down the river
in a covered basket, watched by Moses' older sister. When Pharaoh's daughter
found the basket and Moses in it, his sister offered to find a nurse for Pharaoh's
daughter and brought her mother - i.e., Moses' mother - whom Pharaoh's
daughter offered to pay to nurse Moses for her. So Moses' mother ended up
getting paid to nurse her own son. (see Exodus 2:1-10)
What was Moses like at forty years of age?
"Moses was learned in all the wisdom of the Egyptians, and was
mighty in words and deeds." (Acts 7:22)
Why did Moses flee at the Hebrew's words?
Moses had killed the Egyptian and buried him in the sand, thinking that
nobody had witnessed the murder. When he learned that his crime was known, he fled
to escape being arrested and executed by Pharaoh (see Exodus 2:11-15).
How did Moses react when God told him that He would send him to Egypt to deliver the Hebrews?
At first, he resisted: "Then Moses said to the LORD, 'O my Lord, I
am not eloquent, neither before nor since You have spoken to Your servant;
but I am slow of speech and slow of tongue'" (Exodus 4:10).
Since Acts 7:22 says that he was "mighty in words," was
Moses lying to God about being "slow of speech and slow of tongue"?
No, the Moses who was "mighty in words" had become
"slow of speech and slow of tongue" after 40 years of being a
shepherd, and this wasn't by accident. Relying on the "wisdom of the
Egyptians" (Acts 7:22) and his own words and deeds, Moses
had "supposed that his brethren would have understood that God would
deliver them by his hand" (Acts 7:25). The result was failure,
murder and self-exile. God may have intended for the forty years to be a period
during which Moses is cleansed of the 'wisdom' of Egypt, as well as his
self-reliance, pride and 'natural' skills, so that there would be no mistake
later that Israel was delivered by the supernatural power of God.
