How did Moses mother save his life?

moses mother put him in a basket and put it among the reeds of the nile river until pharoah's daughter found him. (exodus 2:1-10)

20:38-40 ((When We inspired to your mother what We inspired,....[Saying], 'Cast him into the chest and cast it into the river, and the river will throw it onto the bank; there will take him an enemy to Me and an enemy to him.' And I bestowed upon you love from Me that you would be brought up under My eye.....[And We favored you] when your sister went and said, 'Shall I direct you to someone who will be responsible for him?' So We restored you to your mother that she might be content and not grieve. And you killed someone, but We saved you from retaliation and tried you with a [severe] trial. And you remained [some] years among the people of Madyan. Then you came [here] at the decreed time, O Moses))

She also used her posaion to get him an education and help him live a better life than his hebrew brothers and sisters.
She told the truth to honor the hebrew parents sacriface she let him know he was hebrew and then past on their faith to him.
The Exodus would not of happen with out Pharaho's daughter.
