What does Exodus 2:8 mean?

Pharaoh’s daughter came down to bathe at the river. Her maidens walked along by the riverside. She saw the basket among the reeds, and sent her servant to get it.

She opened it, and saw the child, and behold, the baby cried. She had compassion on him, and said, “This is one of the Hebrews’ children.”

Then his sister said to Pharaoh’s daughter, “Should I go and call a nurse for you from the Hebrew women, that she may nurse the child for you?”

Pharaoh’s daughter said to her, “Take this child away, and nurse him for me, and I will give you your wages.” The woman took the child, and nursed it.

The child grew, and she brought him to Pharaoh’s daughter, and he became her son. She named him Moses, and said, “Because I drew him out of the water.”

In those days, when Moses had grown up, he went out to his brothers, and looked at their burdens. He saw an Egyptian striking a Hebrew, one of his brothers.
