Through faith Moses, when he grew to manhood, refused to be known as Pharaoh's daughter's son,

And when he was cast out, Pharaoh's daughter took him up, and nourished him for her own son.

On their second visit Joseph made himself known to his brothers, and thus Joseph's race was revealed to Pharaoh.

And from this we learn that everything is dependent not on man's will or endeavour, but upon God who has mercy. For the Scripture said to Pharaoh,

and rescued him from all his troubles and granted him favor and wisdom in the sight of Pharaoh, king of Egypt, who made him a governor over Egypt and his [i.e., the king's] household.

For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth.
